Build it or buy it?

Building a gaming PC is not cheaper in 2026: Compare Electronic priced like-for-like builds against prebuilts at three budgets on Amazon UK at the time of writing (September 2026), and a system-builder prebuilt undercut the self-build at every tier, by £36.95 to £462.85. The Computek RTX 5060 tower at £797.99 is £357.91 cheaper than its £1,155.90 DIY equivalent, the Vibox Ryzen 7 5700X PC at £1,529.95 is £36.95 under a £1,566.90 build, and the Veno Scorp Gaming PC at £1,649.00 is £462.85 under a £2,111.85 Ryzen 7 7800X3D build.

Building wins only against premium brands, or for buyers who want specific parts, faster memory or an upgrade path. The same £2,111.85 build costs £357.15 less than the Alienware Aurora ACT1250at £2,469.00. System-builder prebuilts win on memory: builders bought DDR4, DDR5 and SSD stock before prices spiked, Tom's Guide reported in December 2025, so their prebuilts carry older-price parts while a DIY builder pays today's retail price. Every DIY total below includes a £119.00 Windows 11 Home licence, because every prebuilt in the comparison ships with Windows 11.

Is it cheaper to build a PC in 2026?

Building a PC in 2026 is not cheaper than buying a system-builder prebuilt at any of Compare Electronic's three tiers: the like-for-like gap runs from £36.95 at 1440p to £462.85 at the high end. Only the Alienware Aurora ACT1250 costs more than its DIY equivalent. The table sums up the comparisons; the line-by-line builds follow further down.

Independent US coverage found the same pattern through 2025 and 2026:

• Tom's Guide(5 December 2025) headlined its US comparison "It is now cheaper to buy a pre-built gaming PC than building one yourself". An MSI RTX 5050 system at $829 cost $895.07 to replicate, and a Skytech RX 9070 XT system at $1,899 cost $1,975.65.
• SlashGear (16 August 2026) priced a Core i5-14400F, RTX 5060 and 32 GB DDR4 prebuilt at about $1,150, against about $1,250 to build.
• Newegg Insider(26 August 2026), a retailer's own guide, concluded: "The long-standing assumption that self-assembly automatically saves money no longer holds reliably."

The UK figures follow the US pattern, with one exception: Tom's Guide found even an Alienware RTX 5070 Ti system at $1,529 undercut its parts in the US, but the UK Alienware Aurora ACT1250 costs £2,469.00 with an RTX 5070, £357.15 more than building. The prebuilt side of the market is ranked in Best prebuilt gaming PC UK 2026.

Why are prebuilt PCs cheaper than building right now?

Prebuilt PCs are cheaper right now because system builders bought memory and SSDs in bulk before the 2025 to 2026 price spike, while a DIY builder pays September 2026 retail prices. Tom's Guide reported in December 2025 that brands build "using the stockpile of RAM and SSDs they already have on their books".

The Crucial Pro DDR5-6000 32 GB kit costs £401.99 on Amazon UK at the time of writing (September 2026), 5.1 times its £79 price in September 2025, and the WD_BLACK SN850X 1TBcosts £178.99. TrendForce's contract-price figures explain the jump:

• Q1 2026: DRAM contract prices up 90 to 95% quarter on quarter (PC DRAM over 100%), NAND up 55 to 60%.
• Q2 2026: DRAM up 58 to 63%, NAND up 70 to 75%.
• Q3 2026: DRAM up 13 to 18%, NAND up 10 to 15%, a slowdown TrendForce put down to consumers reaching their price limit.

In the high-end build below, memory and the SSD account for £608.98 of the £2,111.85 total, or 29%. Those two parts are where a system builder holding older stock gains most. Relief is not close: SK hynix's chief executive said in July 2026 that 2027 will be "the worst year in the industry's history from the supply perspective", Reuters reported. The background is in RAM shortage 2026: why tech is more expensive.

How much does each route cost at 1080p, 1440p and high end?

A like-for-like build costs £1,155.90 at 1080p, £1,566.90 at 1440p and £2,111.85 at the high end, against system-builder prebuilt prices of £797.99, £1,529.95 and £1,649.00. Each DIY build matches the prebuilt's graphics card, memory type and memory capacity. The high-end build uses the same Ryzen 7 7800X3D as the Veno Scorp Gaming PC and Vibox IX-568; the 1080p and 1440p builds use a 10-core Intel Core i5-14400F where the prebuilts use AMD's 6-core Ryzen 5 5500 and 8-core Ryzen 7 5700X. Every build adds a case, a 750 W power supply, a 1 TB NVMe SSD and Windows 11 Home, plus a cooler where the CPU box has none. All prices are Amazon UK at the time of writing (September 2026).

1080p, RTX 5060: the prebuilt wins by £357.91

The Computek RTX 5060 tower costs £797.99 on Amazon UK at the time of writing (September 2026) with a 6-core Ryzen 5 5500, an RTX 5060 with 8 GB of GDDR7, 16 GB of DDR4, a 256 GB SSD plus 1 TB of storage, Wi-Fi and Windows 11. Tom's Hardware's June 2026 GPU hierarchy measured the RTX 5060 at 88.5 fps at 1080p Ultra, which makes this a 1080p high-settings PC.

• The gap: the parts cost £1,155.90, so the Computek RTX 5060 tower is £357.91 cheaper. The parts alone cost 45% more than the whole PC.
• Without Windows: the DIY build is £1,036.90, still £238.91 more than the Computek RTX 5060 tower.
• Where DIY is better: a newer 10-core Core i5-14400F in place of the 6-core Ryzen 5 5500, a full 1 TB NVMe boot drive instead of 256 GB, and a 750 W Corsair RM750e with headroom for a bigger graphics card. NVIDIA recommends 550 W for the RTX 5060, so a cheaper 550 to 650 W supply would narrow the gap but not close it.
• Wi-Fi: the MSI PRO B760M-P DDR4 has no Wi-Fi, while the Computek RTX 5060 tower includes it, so a builder who needs wireless adds the cost of an adapter on top.

1440p, RTX 5070: the prebuilt wins by £36.95

The Vibox Ryzen 7 5700X PC costs £1,529.95 on Amazon UK at the time of writing (September 2026), with an 8-core Ryzen 7 5700X, an RTX 5070 with 12 GB of GDDR7, 32 GB of DDR4 on AMD's AM4 platform, a 1 TB SSD, Wi-Fi and Windows 11. Tom's Hardware's June 2026 GPU hierarchy measured the RTX 5070 at 96.4 fps at 1440p Ultra.

• The gap: the DIY build costs £1,566.90, £36.95 more than the Vibox Ryzen 7 5700X PC, a 2.4% difference.
• Processor:the Vibox Ryzen 7 5700X PC uses a comparable 8-core chip against the DIY build's 10-core Core i5-14400F. With an RTX 5070 at 1440p the graphics card sets the limit in most games.
• Without Windows: the DIY build is £1,447.90, £82.05 under the Vibox Ryzen 7 5700X PC, so a builder who already has a Windows licence for the new PC comes out ahead.
• Wi-Fi: the MSI PRO B760M-P DDR4 has no Wi-Fi, so a builder who needs wireless pays extra for an adapter. That favours the Vibox Ryzen 7 5700X PC.
• The builder's edge is choice: swapping the RTX 5070 for the ASUS Prime Radeon RX 9070 XT OCat £668.99 cuts the DIY total to £1,516.90, £13.05 under the Vibox Ryzen 7 5700X PC. Tom's Hardware's June 2026 GPU hierarchy has the Radeon RX 9070 XT 21% faster at 1440p Ultra (116.5 fps against 96.4 fps) and 8% faster with ray tracing (55.5 fps against 51.5 fps). AMD rates the Radeon RX 9070 XT at 304 W and recommends a 750 W supply, which the RM750e meets.

The two graphics cards are compared in detail in RTX 5070 vs RX 9070 XT, and the wider field is in Best graphics card UK 2026.

High-end 1440p: the Veno Scorp saves £462.85, the Alienware costs £357.15 more

The Veno Scorp Gaming PC costs £1,649.00 on Amazon UK at the time of writing (September 2026) with an 8-core Ryzen 7 7800X3D, an RTX 5070 with 12 GB of GDDR7, 32 GB of Corsair DDR5-5600, a 1 TB NVMe SSD, an 800 W power supply, Wi-Fi and Windows 11 in a Corsair 3000D case. It uses the same processor and graphics card as the DIY build below. The Ryzen 7 7800X3D against the older Ryzen 7 5700X is covered in Ryzen 7 7800X3D vs 5700X gaming PC.

• The gap: the DIY build costs £2,111.85, £462.85 more than the Veno Scorp Gaming PC and £351.90 more than the Vibox IX-568 at £1,759.95, which pairs the same Ryzen 7 7800X3D and RTX 5070 with 32 GB of DDR5, a 1 TB SSD, Wi-Fi and Windows 11. Without the Windows licence the DIY build is £1,992.85, still £343.85 more than the Veno Scorp Gaming PC.
• Faster memory:the DIY build's Patriot Viper Venom kit is rated DDR5-6000 CL30, against DDR5-5600 in the Veno Scorp Gaming PC.
• Parts choice and warranties:every DIY part is a named retail model covered by its own maker, such as 5 years on the WD_BLACK SN850X under Sandisk's datasheet.
• Upgradeability: a later graphics card, memory or processor upgrade starts from a known motherboard and power supply.

Against the Alienware Aurora ACT1250, building saves £357.15

The Alienware Aurora ACT1250 costs £2,469.00 on Amazon UK at the time of writing (September 2026) with a 20-core Core Ultra 7 265KF, an RTX 5070, 32 GB of DDR5-5200, a 1 TB SSD, a 240 mm liquid cooler, a 1,000 W Platinum power supply, a Z890 motherboard, Wi-Fi 7 and 1 Year Alienware Care. That is £820.00 more than the Veno Scorp Gaming PC with the same graphics card and memory capacity. The Core Ultra 7 265KF is the Core Ultra 7 265K without integrated graphics.

• The gap: the DIY build costs £2,111.85, £357.15 less than the Alienware Aurora ACT1250, or £476.15 less without the Windows licence.
• Faster gaming CPU:Tom's Hardware's CPU hierarchy, updated 26 August 2026, scores the Ryzen 7 7800X3D at 85.6% and the Core Ultra 7 265K at 70.3%, relative to the Ryzen 7 9850X3D at 100%, in a 17-game average at 1080p on an RTX 5090. With an RTX 5070 at 1440p the graphics card sets the limit in most games, so the gap in play will usually be smaller.
• Faster memory:Dell's manual states that the Alienware Aurora ACT1250's processors limit memory to 5200 MT/s, with faster speeds only through XMP on Dell-qualified modules. The DIY build's Patriot kit is rated DDR5-6000 CL30.
• Same connectivity:the ASUS TUF Gaming B850-Plus WiFi matches the Alienware Aurora ACT1250's Wi-Fi 7 and 2.5 Gb Ethernet.
• Where the Alienware Aurora ACT1250 is ahead: a 1,000 W Platinum supply against 750 W Gold, a 240 mm liquid cooler, and one company responsible for the whole machine.

The upgrade path also favours the AMD machines. The DIY build, the Veno Scorp Gaming PC and the Vibox IX-568 all use AMD's AM5 socket, which AMD has committed to supporting through 2029, while Intel's next desktop generation is reported to move to a new LGA1954 socket. CPU choice is covered in Best CPU for gaming UK 2026 and board choice in Best motherboard for gaming UK 2026.

What are the hidden costs of building a PC, and of buying one?

The biggest hidden cost of building is the £119.00 Windows 11 Home licence; the biggest hidden cost of buying is what a prebuilt leaves out, usually boot-drive space, memory speed and upgrade room.

Hidden costs of building

• Windows: the Windows 11 Home digital licence costs £119.00 on Amazon UK at the time of writing (September 2026), and Windows 11 Pro costs £219.00.
• Tools: a Phillips #2 screwdriver for case screws and a Phillips #1 for M.2 screws, per PCWorld.
• Time:4 to 8 hours for a first build, by retailer and hobby guides' estimates, plus driver and Windows setup.
• Many warranties: every part is claimed separately against its own seller, and a fault has to be traced to one part before any claim starts.
• Assembly risk:a part damaged during assembly is the builder's cost, not the retailer's.

Hidden costs of buying

• Small boot drives: the Computek RTX 5060 tower boots from a 256 GB SSD. Games belong on its second drive or a new NVMe SSD; picks are in Best NVMe SSD for gaming UK 2026.
• Slower memory: the Veno Scorp Gaming PC ships with DDR5-5600 and the Alienware Aurora ACT1250 with DDR5-5200, where the high-end DIY build uses DDR5-6000 CL30.
• Proprietary parts: the Alienware Aurora ACT1250 uses a non-ATX power supply and an own-brand motherboard, so a future power supply or motherboard swap is not a standard retail job.
• Shorter cover at the brand end: 1 Year Alienware Care on the Alienware Aurora ACT1250, against 3 years of parts and labour as standard at Scan 3XS, Overclockers UK and CCL.

Is a prebuilt gaming PC worse quality than a self-build?

A prebuilt is not automatically worse quality, but it usually saves money on the parts buyers check last: the power supply, the boot drive and the motherboard. In every one of Compare Electronic's comparisons the graphics card and memory capacity match; the differences sit in the supporting parts listed above. The Alienware Aurora ACT1250 goes furthest from standard parts. Dell's owner's manual lists its power supply as a "1000 W SFFX Platinum" unit with 12 V-only outputs, where a standard ATX supply also provides 3.3 V and 5 V rails. PCGamesN describes an "own-brand Alienware micro-ATX motherboard", and TechRadar's review calls it a "proprietary motherboard".

The brand differences between Alienware, ASUS ROG and MSI are covered in ASUS ROG vs MSI vs Alienware.

Which UK PC builder has the best warranty?

Chillblast has the longest standard warranty of the major UK system builders at 5 years, and Scan 3XS, Overclockers UK and CCL each give 3 years of parts and labour. PCSpecialist's standard cover is 1 year parts and 3 years labour, not 3 years of parts.

Warranty sits on top of statutory rights. Which? summarises the Consumer Rights Act 2015 like this:

Which? notes that these claims go against the retailer, not the manufacturer. A prebuilt puts the whole PC under one claim with one seller. A self-build splits it into one claim per part, and the builder has to identify which part failed.

How hard is it to build a PC for the first time?

A first PC build is manageable for anyone patient with small screws and cables: it takes an afternoon to a day and needs one screwdriver. Retailer and hobby guides put a build at 2 to 3 hours for experienced hands and 4 to 8 hours for a first-timer, with cable connections the slowest step.

• Tools:PCWorld's Alaina Yee writes that a Phillips #2 screwdriver fits "nearly all screws in a computer case"; M.2 drive screws need a Phillips #1, and a magnetised tip helps.
• Monitor cable:plugging the monitor into the motherboard instead of the graphics card is "arguably the most common rookie mistake", according to PC Gamer's list of 11 building mistakes.
• Memory:PC Gamer advises installing two sticks in slots two and four for dual channel, then enabling XMP or EXPO, after a BIOS update, because some AMD CPUs were "burned by overenthusiastic EXPO voltages".
• Planning errors: How-To Geek (31 October 2025) lists undersizing the power supply, fitting a liquid cooler where air would do, and overspending on the motherboard.
• No start at first boot:a forgotten 8-pin CPU power cable stops a PC from starting, a problem raised on Tom's Hardware's forum.

Does a new PC need a Windows licence, and is Windows 10 still safe?

A self-built PC needs a Windows licence, which costs £119.00 for Windows 11 Home on Amazon UK at the time of writing (September 2026); Windows 10 stays safe only with Extended Security Updates, which now run to 12 October 2027.

• Prebuilts include it: the Computek RTX 5060 tower, Vibox Ryzen 7 5700X PC, Veno Scorp Gaming PC, Vibox IX-568 and Alienware Aurora ACT1250 all ship with Windows 11, so every DIY total in the tables above carries £119.00 that the prebuilt price already covers.
• Windows 10 support: Microsoft ended standard support on 14 October 2025 and quietly extended consumer ESU to 12 October 2027 (Windows Latest, 25 June 2026).
• ESU in the UK: free when PC settings sync to a Microsoft account, or 1,000 Microsoft Rewards points, or a one-off $30 in local currency. One ESU licence covers up to 10 devices. The no-strings free option offered in the European Economic Area does not apply to the UK.

A new gaming PC should run Windows 11. Windows 10 on new hardware only buys time until October 2027.

Who should build a gaming PC and who should buy one?

Most buyers should buy a system-builder prebuilt in 2026, because it costs less than a matching self-build at every tier Compare Electronic priced; building suits buyers who want specific parts, faster memory or an upgrade path, and anyone weighing a premium brand such as Alienware.

• The Computek RTX 5060 tower suits first-time PC owners, gift buyers and any 1080p budget under £1,000; a matching DIY build costs £357.91 more. More options at this level are in Best cheap gaming PC UK 2026.
• The Vibox Ryzen 7 5700X PC suits 1440p buyers who want Wi-Fi, Windows and one seller, with no assembly, for £36.95 less than DIY.
• A Radeon RX 9070 XT build suits 1440p buyers happy to assemble: 21% more 1440p performance than the RTX 5070, for £13.05 less than the Vibox Ryzen 7 5700X PC.
• The Veno Scorp Gaming PC suits high-end 1440p buyers who want a Ryzen 7 7800X3D and RTX 5070 for the least money: £462.85 less than DIY and £820.00 less than the Alienware Aurora ACT1250.
• A Ryzen 7 7800X3D build suits buyers who want DDR5-6000 CL30 memory, named parts with their own warranties and an AM5 upgrade path; it costs £357.15 less than the Alienware Aurora ACT1250.

Verdict: build or buy a gaming PC in 2026?

Buy from a system builder, unless the alternative is a premium brand. In September 2026 Amazon UK system-builder prebuilts undercut a like-for-like self-build at every tier Compare Electronic priced, by £36.95 to £462.85, because builders bought memory and SSDs before the 2025 to 2026 price spike. The Computek RTX 5060 tower at £797.99 is £357.91 under its parts, the Vibox Ryzen 7 5700X PC at £1,529.95 is £36.95 under, and the Veno Scorp Gaming PC at £1,649.00 is £462.85 under a £2,111.85 Ryzen 7 7800X3D build. Building wins against the Alienware Aurora ACT1250 at £2,469.00, by £357.15, and for buyers who want a Radeon RX 9070 XT, DDR5-6000 CL30 memory, per-part warranties or an upgrade path. All prices are Amazon UK at the time of writing (September 2026).
