The NZXT shortlist

NZXT is worth buying for cases and coolers first: the NZXT H9 Flow is the best NZXT product for most buyers, at £88.99 on Amazon UK at the time of writing (October 2026). NZXT fits three 140 mm fans and one 120 mm fan, 420 mm radiator mounts on the top and front-right, 459 mm of GPU clearance and back-connect motherboard support into a 76.7-litre dual-chamber case.

The NZXT H6 Flow at £84.98 is the compact alternative, the NZXT H7 Flow at £62.99 the airflow value pick and the NZXT H5 Flow at £49.95 the budget case. The NZXT Kraken Plus 360at £129.95 is the best NZXT cooler. NZXT's weak points are software-dependent coolers, 3-pin case fans and a record that includes a recall and a class-action settlement.

Is NZXT a good brand?

Yes for cases and Kraken coolers, with two blemishes on its record. The strengths and weaknesses, from NZXT's spec sheets and named reports:

• Cases: every H-series case here ships with fans, from two in the NZXT H5 Flow to four in the NZXT H9 Flow, per NZXT.
• Coolers: NZXT gives the Kraken Plus and Kraken Elite a 6-year warranty, three times the 2 years on its cases.
• Software: the Kraken Plus and Elite rely on NZXT CAM for pump, fan and screen control, per NZXT.
• Record: a 2021 recall of the NZXT H1 case and the 2026 Flex rental settlement, both covered below.

Rival brands are covered in the best Corsair products UK 2026 and best MSI products UK 2026 guides.

1. NZXT H9 Flow - best NZXT product overall

The NZXT H9 Flow costs £88.99 on Amazon UK at the time of writing (October 2026) in black, the 2025 version (CM-H92FB-01). NZXT splits the case into two chambers, with the power supply and drives behind the motherboard, and angles three 140 mm intake fans from the front-right side. That leaves room for a 420 mm radiator on the top, another at the front-right, a 459 mm graphics card and an E-ATX board up to 277 mm.

The NZXT H9 Flow is the only one of the four ATX cases here with back-connect support, for ASUS BTF and MSI Project Zero boards that move the connectors to the rear. The trade-off is size: 12.49 kg and 481 mm deep need a big desk. It suits showcase builds with a large GPU and a 360 mm or 420 mm AIO.

2. NZXT H6 Flow - best compact NZXT showcase case

The NZXT H6 Flow costs £84.98 on Amazon UK at the time of writing (October 2026) in black. NZXT wraps the front corner in glass and mounts three 120 mm intake fans at the front-right, in a dual-chamber case 24.9 litres smaller than the NZXT H9 Flow.

The compromises follow from the size: 365 mm of GPU clearance, a 360 mm top radiator limit and no back-connect support, per NZXT. At £4.01 less than the NZXT H9 Flow, the NZXT H6 Flow suits buyers whose desk sets the limit rather than their budget.

3. NZXT H7 Flow - best NZXT airflow case for the money

The NZXT H7 Flow costs £62.99 on Amazon UK at the time of writing (October 2026) in black, the 2024 version (CM-H72FB-01). It is a conventional mesh-fronted tower rather than a showcase: three 120 mm intake fans, a 420 mm front radiator mount and three bottom fan mounts that NZXT aims at the graphics card.

Its 185 mm cooler clearance is the highest of any NZXT case here, so large dual-tower air coolers fit. The NZXT H7 Flow costs £26.00 less than the NZXT H9 Flow and suits buyers who rank temperatures above the view.

4. NZXT H5 Flow - best budget NZXT case

The NZXT H5 Flow costs £49.95 on Amazon UK at the time of writing (October 2026) in black, the 2024 version. NZXT fits two F120Q fans, a 360 mm front radiator mount and 410 mm of GPU clearance into 45.0 litres, the smallest ATX case in NZXT's range here.

The NZXT H7 Flow costs £13.04 more and adds a third fan, a 420 mm front mount and 15 mm more cooler height, which suits most buyers unless desk space or budget is tight. Rival budget towers are ranked in the best mid-tower PC case UK 2026 guide.

NZXT H6 Flow vs H9 Flow: which should you buy?

The NZXT H9 Flow, for most buyers: it costs £4.01 more than the NZXT H6 Flow and adds a fourth fan, 420 mm radiator support, 94 mm more GPU clearance and back-connect support. NZXT's spec sheets side by side:

The NZXT H6 Flow wins only on footprint: 24.9 litres smaller and 3.07 kg lighter. Both are dual-chamber designs with NZXT's 2-year case warranty. Full-size alternatives are in the best full-tower PC case UK 2026 guide.

Which NZXT case suits a mini-ITX build?

The NZXT H2 Flow, at £129.99 on Amazon UK at the time of writing (October 2026) in white. NZXT rates it at 20.7 litres, with a PCIe 5.0 riser for a graphics card up to 331 mm long and 65 mm thick, a 280 mm front radiator mount, two F120Q fans on top and an SFX or SFX-L power supply up to 130 mm. Air coolers are limited to 75 mm.

The riser matters because of NZXT's history: the 2021 recall of the NZXT H1 centred on its PCIe riser assembly. Rival small cases are ranked in the best mini-ITX case UK 2026 guide, and PC case sizes explained covers what fits each size.

Which NZXT Kraken cooler is worth buying?

The NZXT Kraken Plus 360, at £129.95 on Amazon UK at the time of writing (October 2026). NZXT gives it the same 1,200 to 2,800 RPM pump, three F120P fans and 6-year warranty as the Kraken Elite 360, with a smaller 1.54-inch 240 x 240 screen.

• NZXT Kraken Core 360 RGB, £69.95 (budget): a fixed 3,100 RPM pump and an F360 RGB Core fan array rated at 75.05 CFM and 31.9 dBA, run from motherboard headers with no software, and a 5-year warranty.
• NZXT Kraken Plus 360, £129.95 (best): a 1.54-inch 240 x 240 30 Hz TFT screen and three F120P fans rated at 73.47 CFM and 30.0 dBA, £60.00 more than the Kraken Core.
• NZXT Kraken Elite 360, £219.99 (flagship): a 2.72-inch 640 x 640 60 Hz IPS screen rated at 690 nits, with the same pump and fans; the £90.04 gap over the Kraken Plus 360 buys the screen alone.

All three fit AMD AM5 and AM4 and Intel LGA 1851 and 1700, per NZXT. The CPUs worth cooling are in the best CPU for gaming UK 2026 guide.

Are NZXT keyboards, mice and headsets any good?

They are good value at current Amazon UK prices, but not class leaders. The picks, at Amazon UK prices in October 2026:

• NZXT Lift Elite Wireless, £47.96 (white): 57 g, a 26,000 DPI PixArt PAW3395 sensor, 4,000 Hz wireless and 8,000 Hz wired polling, and optical switches rated for 100 million clicks. NZXT rates the battery at 70 hours at 1,000 Hz or 22 hours at 4,000 Hz. The black version costs £58.90.
• NZXT Lift 2 Symm, £39.98 (wired): 58 g with 8,000 Hz polling and a 26,000 DPI sensor, per NZXT.
• NZXT Function 2, £39.99 (full-size, UK layout): 40 g linear optical switches with 1 mm or 1.5 mm actuation, 8,000 Hz polling, hot-swap sockets, PBT doubleshot keycaps and a 3 mm aluminium top plate. NZXT launched it at $139.99 in February 2024.
• NZXT Relay, £50.00 (wired headset): a closed-back design with Hi-Res Audio certification from the Japan Audio Society, DTS Headphone:X spatial audio and EQ in NZXT CAM.

Is the NZXT C850 Gold Core a good power supply?

Yes for a quiet single-GPU build: the NZXT C850 Gold Core costs £89.99 on Amazon UK at the time of writing (October 2026). NZXT lists ATX 3.1 with a dual-colour 12V-2x6 connector, 80 Plus Gold and Cybenetics Platinum efficiency, a Cybenetics A++ noise rating below 15 dBA and a 135 mm fluid dynamic bearing fan with Zero RPM mode. Its modular cables belong in NZXT units only; sleeving options are in the best sleeved PSU cables UK 2026 guide.

How much does an NZXT case, cooler and PSU cost together?

£209.89 for a budget NZXT shell, £282.93 for a value build and £398.97 for a showcase build. Compare Electronic paired each case with a 360 mm Kraken that fits its radiator mounts, per NZXT:

The value build is the sweet spot: it keeps an LCD cooler and a 420 mm-capable case for £116.04 less than the showcase build. NZXT also sells its Player One, Player Two and Player Three prebuilt PCs through its own website; the case for building is set out in build vs buy a gaming PC UK 2026, and prebuilt alternatives in the best gaming PC UK 2026 guide.

What does NZXT do better or worse than rivals?

NZXT does fan-equipped cases and long cooler warranties well, and does worse on fan control, peripherals' headline specs and its record. The facts, with sources:

• Better, coolers: NZXT gives the Kraken Plus 360 a screen and a 6-year warranty for £129.95.
• Better, mouse weight: the NZXT Lift Elite Wireless weighs 57 g, 3 g less than the 60 g Logitech G PRO X SUPERLIGHT 2, per both makers.
• Worse, wireless polling: the Lift Elite reaches 4,000 Hz wirelessly; Logitech rates the PRO X SUPERLIGHT 2 at 8,000 Hz.
• Worse, keyboards: the Function 2 offers two actuation points, 1 mm or 1.5 mm, while magnetic boards such as the Logitech G PRO X TKL RAPID set actuation per key and add Rapid Trigger.
• Worse, case fans:NZXT's case-version fans are 3-pin DC, controlled by voltage rather than PWM, per NZXT's H9 Flow listing.
• Worse, back-connect price: Corsair validates its 3500X for ASUS BTF and MSI Project Zero boards at £58.37; the cheapest NZXT case here with that support is the £88.99 H9 Flow.
• Worse, the H1 recall: the US Consumer Product Safety Commission announced on 12 February 2021 that NZXT was recalling about 32,000 H1 cases in the US and 1,024 in Canada, because screws attaching the PCIe riser assembly could short the circuit board. NZXT had 11 reports of overheating or fire and no injuries.
• Worse, NZXT Flex: after a 2024 Gamers Nexus investigation, NZXT and billing partner Fragile agreed a $3.45 million preliminary settlement covering nearly 20,000 rental customers, TechSpot reported on 13 April 2026.

Logitech's range is compared in the best Logitech products UK 2026 guide.

Who should skip NZXT?

• Software-averse builders: the Kraken Plus and Elite need NZXT CAM for their screens; the Kraken Core does not.
• Competitive wireless mouse players: the Lift Elite tops out at 4,000 Hz wireless.
• Big GPUs on a small desk: the NZXT H6 Flow takes cards up to 365 mm only.
• Back-connect builds on a budget: NZXT lists no back-connect support for the H5, H6 or H7 Flow.

Verdict

The NZXT H9 Flow at £88.99 is the best NZXT product: four fans, 420 mm radiator mounts and back-connect support for £4.01 more than the NZXT H6 Flow. The NZXT H7 Flow at £62.99 is the airflow value pick, the NZXT H5 Flow at £49.95 the budget case and the NZXT Kraken Plus 360at £129.95 the cooler to pair with any of them. NZXT's peripherals are cheap at current prices but trail Logitech on headline specs.
