The PC case shortlist

The best PC case in the UK is the Lian Li Lancool 217 at £109.99 on Amazon UK at the time of writing (October 2026): a mid tower with five fans in the box, 380 mm of graphics card clearance, 180 mm of CPU cooler clearance and support for back-connect motherboards. The best budget PC case is the MSI MAG Forge 320R Airflow at £69.98, with four ARGB fans fitted.

Each size has its own pick: the Phanteks NV7 D-RGB at £159.95 is the best full tower, the Lian Li A3-mATX at £73.99 the best micro ATX case and the Cooler Master NR200P V3 at £169.89 the best mini ITX case. Every spec below comes from the manufacturer's spec page, every pick links to its full format guide, and the decision table after the picks matches a build to a case.

What is the best PC case in the UK?

The Lian Li Lancool 217 is the best PC case in the UK because it combines the three things buyers usually pay extra for: fans in the box, a mesh front, and room for the longest 2026 graphics cards. It is a mid tower, the size that suits most builds, since it takes an ATX motherboard, a standard ATX power supply and a 360 mm radiator.

The picks below cover one case per size, plus two cheaper mid towers. How motherboard sizes map to case sizes, with litres for each format, is explained in PC case sizes explained.

1. Lian Li Lancool 217 - best PC case overall

The Lian Li Lancool 217 costs £109.99 on Amazon UK at the time of writing (October 2026) in black with walnut wood trim. Lian Li fits five fans: two 170 mm fluid dynamic bearing fans behind the perforated mesh front, rated at 142.56 CFM each, two 120 mm fans above the PSU shroud aimed at the graphics card, and a 140 mm exhaust. The front fans move without tools, up to favour the CPU or down to favour the graphics card.

Clearance covers almost every 2026 build. Lian Li lists 380 mm for the graphics card, enough for the 357.6 mm ASUS ROG Astral RTX 5090, and 180 mm for a tower air cooler. Back-connect support for ATX and Micro ATX boards is new over the Lancool 216. The limits are radiator space, which Lian Li lists on the top only, and a one-year chassis warranty. The full ranking is in Best mid tower PC case UK 2026.

2. MSI MAG Forge 320R Airflow - best budget PC case

The MSI MAG Forge 320R Airflow costs £69.98 on Amazon UK at the time of writing (October 2026) and is the best budget PC case because it ships ready to run. MSI fits three 120 mm ARGB fans behind the mesh front and a fourth at the rear, with a control board that runs six ARGB devices. That works out at £17.50 per included fan, the lowest of any case in this guide.

MSI's datasheet lists 390 mm of graphics card clearance, 160 mm for a CPU cooler and a 360 mm radiator on top, with 11 fan mounts in all. The savings show at the front panel, which has two USB-A ports and no USB-C, and in board support, which stops at ATX. A 160 mm cooler limit rules out the tallest tower coolers, so check the cooler height before buying.

3. Phanteks NV7 D-RGB - best full tower PC case

The Phanteks NV7 D-RGB costs £159.95 on Amazon UK at the time of writing (October 2026) and is the best full tower because it fits the most hardware of any case here. Phanteks lists a 450 mm graphics card, a 185 mm CPU cooler, a 255 mm power supply and three 360 mm radiators at once, on the top, side and bottom. Glass on the front and side shows off the build, and a 65 mm gap under the case feeds the bottom fans that cool the graphics card.

The NV7 ships without fans, so a full set adds to the £159.95, and at 16.90 kg it weighs more than twice as much as the 7.28 kg NZXT H5 Flow. It suits custom water cooling, E-ATX boards and multi-radiator builds rather than a single graphics card and an air cooler. The other full towers are ranked in Best full tower PC case UK 2026.

4. Lian Li A3-mATX - best micro ATX PC case

The Lian Li A3-mATX costs £73.99 on Amazon UK at the time of writing (October 2026) and is the best micro ATX case because it fits mid tower hardware into 26.3 litres, less than half the volume of the Lancool 217. Lian Li, which designed the case with DAN Cases, lists a 415 mm graphics card, a 165 mm CPU cooler and a 360 mm radiator on the top or side. It takes a standard ATX power supply as well as SFX, which keeps the build cheaper.

The compromises are four expansion slots, Micro ATX and Mini ITX boards only, and no fans in Lian Li's listing. Lian Li also notes that a 25 mm fan in the bottom mount limits the graphics card to 61 mm thick, or three slots. The full ranking is in Best micro ATX case UK 2026.

5. Cooler Master NR200P V3 - best mini ITX PC case

The Cooler Master NR200P V3 costs £169.89 on Amazon UK at the time of writing (October 2026) and is the best mini ITX case for a full-power gaming PC in 18.62 litres. The graphics card mounts vertically on an included PCIe 5.0 riser, with room for a card 361.5 mm long, 160 mm high and 3.8 slots thick. The 357.6 mm, 3.8-slot ASUS ROG Astral RTX 5090 sits inside all three limits.

The trade-offs are price, the highest of the five picks, and the cooling layout. Cooler Master lists 70 mm of air cooler clearance, so the NR200P V3 is built around a 240 mm or 280 mm liquid cooler on the roof, and it needs an SFX or SFX-L power supply. Cooler Master lists no fans in the box. The full ranking is in Best mini ITX case UK 2026.

Which cheaper mid towers are worth buying?

Two mid towers undercut the budget pick: the NZXT H5 Flow at £49.95 and the Corsair 3500X at £58.37 on Amazon UK at the time of writing (October 2026). Both add front USB-C, which the MSI MAG Forge 320R Airflow lacks, and both fit a longer graphics card.

• NZXT H5 Flow (£49.95). NZXT lists a 45.0-litre compact mid tower with ultra-fine mesh on the front, top and side, two F120Q fans, a 360 mm radiator mount at the front, 410 mm of graphics card clearance, 170 mm for a CPU cooler and a 20 Gbps USB-C port. NZXT confirms it has no back-connect support.
• Corsair 3500X (£58.37). Corsair lists a panoramic glass mid tower with 425 mm of graphics card clearance, 170 mm for a cooler, 360 mm radiator mounts on the top and side, and support for ASUS BTF, MSI Project Zero and Gigabyte Project Stealth back-connect boards. It includes no fans.

The Corsair 3500X costs more than its price suggests. With an ARCTIC P12 PWM PST five-pack at £42.80 on Amazon UK, the 3500X comes to £101.17, just £8.82 less than the Lancool 217 with its five fans. The NZXT H5 Flow is the better cheap case for an air-cooled build; the 3500X suits a back-connect build on a tight budget.

Which PC case is right for your build?

Match the case to the motherboard first, then to the graphics card and CPU cooler. Compare Electronic's decision table pairs seven common builds with the case in this guide that fits each one at the lowest price, and links to the full guide for that format.

Which PC case gives the most for the money?

The MSI MAG Forge 320R Airflow gives the most per pound: £17.50 per included fan, against £22.00 for the Lian Li Lancool 217 and £24.98 for the NZXT H5 Flow. Compare Electronic's table divides each Amazon UK price by the fans in the box and lists the features that separate the cheap cases from the dear ones.

Fans are the hidden cost of a cheap case. A case with none needs fans bought separately before it can move air: the ARCTIC P12 PWM PST five-pack costs £42.80 on Amazon UK at the time of writing (October 2026), which lifts the Corsair 3500X from £58.37 to £101.17 and the Phanteks NV7 D-RGB from £159.95 to £202.75. On that measure the Lancool 217 at £109.99, with two larger 170 mm fans included, is better value than it first looks.

How do you choose a PC case?

Choose in this order: motherboard size, graphics card length, CPU cooler height and radiator size, then airflow, fans and front ports. The first four are hard limits printed on every manufacturer spec page; the rest are preferences.

• Motherboard size. ATX boards measure 305 x 244 mm, Micro ATX 244 x 244 mm and Mini ITX 170 x 170 mm. E-ATX has no single standard, so case makers quote a width: 277 mm for the NZXT H5 Flow and Corsair 3500X, 280 mm for the Lian Li Lancool 217.
• Graphics card length. NVIDIA lists the RTX 5090 Founders Edition at 304 mm and ASUS lists the ROG Astral RTX 5090 at 357.6 mm. Front radiators cut the usable length: NZXT says its H3 Flow fits a 377 mm card with no front fans but 317 mm with a front radiator and fans. Cards are ranked in Best graphics card UK 2026.
• CPU cooler height.Limits run from 70 mm in the Cooler Master NR200P V3 to 185 mm in the Phanteks NV7 D-RGB. Compare the cooler's height on its spec page with the case's figure.
• Radiator support.A 360 mm all-in-one cooler needs a 360 mm mount: on top in the MSI MAG Forge 320R Airflow and Lancool 217, at the front in the NZXT H5 Flow, and on the top or side in the Corsair 3500X. NZXT allows 55 mm for radiator plus fan on the H5 Flow's roof.
• Airflow. Mesh fronts let intake fans pull air straight in. The Lancool 217, MAG Forge 320R Airflow and H5 Flow use mesh fronts; the Corsair 3500X and Phanteks NV7 D-RGB use glass fronts and draw air through side and bottom mounts.
• Front USB-C. Six of the seven cases here have a front USB-C port; the MAG Forge 320R Airflow has two USB-A ports only. The NZXT H5 Flow and NR200P V3 run theirs at 20 Gbps. The port works only when the motherboard has a front USB-C header.

Do you need a back-connect or dual-chamber case?

Only for a show build. Back-connect motherboards, sold as ASUS BTF, MSI Project Zero and Gigabyte Project Stealth, move the power and fan connectors to the back of the board, so no cables cross the front of the build. The case needs matching cut-outs in its motherboard tray: the Lian Li Lancool 217 takes ATX and Micro ATX back-connect boards and the Corsair 3500X lists all three families, while NZXT says the H5 Flow takes none.

A dual-chamber case moves the power supply, drives and most cables into a second chamber behind the motherboard tray, which NZXT says gives an open, uncluttered view and far more room for cables. The NZXT H6 Flow and H9 Flow are dual-chamber cases; NZXT's range is covered in Best NZXT products UK 2026. Builders who keep a standard board can tidy the view with custom cables, compared in Best sleeved PSU cables UK 2026, and standard boards are ranked in Best motherboard for gaming UK 2026.

Verdict

The Lian Li Lancool 217 at £109.99 is the best PC case in the UK for 2026: five fans, 380 mm of graphics card clearance, back-connect support and front USB-C in a mid tower. The MSI MAG Forge 320R Airflow at £69.98 is the best budget PC case, with four fans at £17.50 each. Other sizes have their own pick: the Phanteks NV7 D-RGB (£159.95) for a full tower, the Lian Li A3-mATX (£73.99) for micro ATX and the Cooler Master NR200P V3 (£169.89) for mini ITX.
