Compare Electronic ranked five mid towers from Lian Li, NZXT, Corsair, Fractal Design and Phanteks on manufacturer clearance figures, cooling mounts, included fans and Amazon UK price. Five clear the 357.6 mm ASUS ROG Astral RTX 5090; the Fractal Design North does not. The full shortlist across every size sits in Best PC case UK 2026.
What is the best mid tower PC case in 2026?
The best mid tower PC case in 2026 clears a long graphics card, takes a 360 mm radiator and ships with at least three fans, and the Lian Li Lancool 217 does all three for £109.99, with 380 mm of GPU room and five fans. The ranking used four criteria:
- Clearance: GPU length of 355 mm or more, and the CPU cooler height the manufacturer lists.
- Cooling: a 360 mm radiator mount and the number of fan positions.
- Fans in the box: counted and priced per fan.
- Connectivity: front USB-C on every pick, and back-connect board support where listed.
Mid towers in this guide measure 42 to 57.7 litres, against 78.9 litres for a Phanteks NV7 full tower. The size classes are explained in PC case sizes explained.
1. Lian Li Lancool 217 - best mid tower PC case overall
Lian Li Lancool 217 specifications
- Dimensions: 482 x 238 x 503 mm (D x W x H), about 57.7 litres
- Motherboards: SSI-EEB (up to 330 mm wide), E-ATX, ATX, micro ATX, mini ITX; back-connect ATX and micro ATX
- GPU clearance: 380 mm; CPU cooler: 180 mm
- Radiator: top 360, 280 or 240 mm
- Fans included: 2 x 170 mm front, 2 x 120 mm bottom, 1 x 140 mm rear
- Front I/O: 2 x USB 3.0, 1 x USB-C, audio
- Power supply: ATX up to 220 mm (180 mm in rotated mode)
The Lian Li Lancool 217 costs £109.99 on Amazon UK at the time of writing (October 2026), and its five fans are the reason it ranks first. Two 170 mm fans pull air through the mesh front, two 120 mm fans sit on the power supply shroud under the graphics card, and a 140 mm fan sits at the rear. At £22.00 per included fan, it needs no extra spend before the first boot.
Lian Li lists 380 mm of GPU clearance, 180 mm for air coolers and board support up to 330 mm wide SSI-EEB, which none of the five cases in the full tower guide lists. The PCIe bracket rotates 90 degrees for a vertical graphics card, and the power supply mount rotates too. The limit is radiators: Lian Li lists the roof as the only radiator position, so a 360 mm AIO goes on top.

2. NZXT H6 Flow - best dual-chamber mid tower
NZXT H6 Flow specifications
- Dimensions: 435 x 287 x 415 mm, 51.8 litres, 9.42 kg (NZXT)
- Motherboards: ATX, micro ATX, mini ITX; no back-connect
- GPU clearance: 365 mm; CPU cooler: 163 mm
- Radiators: top up to 360 mm (30 mm thick), rear 120 mm
- Fans included: 3 x F120Q 120 mm
- Front I/O: 2 x USB 3.2 Type-A, 1 x USB 3.2 Type-C, headset jack
- Power supply: ATX up to 200 mm
The NZXT H6 Flow costs £84.98 on Amazon UK at the time of writing (October 2026). It is a dual-chamber case: the power supply and spare cables sit behind the motherboard tray, and the front corner is glass, so the build is on show from two sides. NZXT fits three F120Q 120 mm fans as intakes along the front-right side.
The dual-chamber layout makes the H6 Flow short and wide: 415 mm tall and 287 mm wide, with 365 mm of GPU clearance and a 360 mm radiator mount in the roof. Air cooler clearance is 163 mm, which rules out the tallest twin-tower coolers, and NZXT lists no back-connect support. For a glass showcase with standard boards at under £90, it is the strongest option.

3. Corsair FRAME 4000D RS ARGB - best modular mid tower
Corsair FRAME 4000D RS ARGB specifications
- Dimensions: 490 x 239 x 486 mm (L x W x H), 10 kg (Corsair)
- Motherboards: E-ATX (305 x 277 mm), ATX, micro ATX, mini ITX; ASUS BTF, MSI Project Zero, Gigabyte Project Stealth
- GPU clearance: 430 mm; CPU cooler: 170 mm
- Radiators: 360 mm front, top and side; 140 mm rear
- Fans included: 3 x RS120 ARGB; mounts for 12 x 120 mm
- Front I/O: 1 x USB 3.2 Gen 2 Type-C, 2 x USB 3.2 Gen 1 Type-A
- Power supply: ATX up to 220 mm
The Corsair FRAME 4000D RS ARGB costs £89.99 on Amazon UK at the time of writing (October 2026) in white; the black version is £94.96. Corsair's InfiniRail system replaces fixed screw holes on the front and roof with a steel rail, so fans slide to any position, and the front takes 200 mm fans. The front I/O panel and motherboard tray are replaceable parts.
The FRAME 4000D has the most room of the mid towers here: 430 mm for graphics cards, 170 mm for coolers and three 360 mm radiator positions, two of them usable at once. Corsair claims the 3D Y-pattern front panel flows up to 12% more air than the older 4000D Airflow panel, and a GPU anti-sag arm comes in the box. At £30.00 per included fan, it is the best case to grow a build in.

4. Fractal Design North - best looking mid tower
Fractal Design North (Charcoal Black TG) specifications
- Dimensions: 447 x 215 x 469 mm, 42 litres, 7.7 kg (Fractal Design)
- Motherboards: ATX, micro ATX, mini ITX
- GPU clearance: 355 mm (300 mm with a 360 mm front radiator); CPU cooler: 145 mm
- Radiators: front up to 360 mm, top up to 240 mm, rear 120 mm
- Fans included: 2 x Aspect 14 PWM
- Front I/O: 2 x USB-A 5 Gbps, 1 x USB-C 20 Gbps, audio and mic jacks
- Power supply: ATX up to 255 mm
The Fractal Design North costs £119.99 on Amazon UK at the time of writing (October 2026) in Charcoal Black with a dark tempered-glass side. Its front is a row of walnut slats with brass details, and at 42 litres it is the smallest ATX case here. The front USB-C port runs at 20 Gbps, double the 10 Gbps of a USB 3.2 Gen 2 port.
The North gives up room for its looks. Fractal lists 145 mm for CPU coolers, the lowest of the five, and 355 mm for graphics cards, falling to 300 mm with a 360 mm front radiator. Two Aspect 14 fans come in the box, so each included fan costs £60.00, the highest of the ATX picks. Buyers with a mid-range graphics card and a compact cooler lose nothing.

5. Phanteks XT Pro Ultra - best value mid tower with fans
Phanteks XT Pro Ultra specifications
- Dimensions: 450 x 230 x 500 mm, about 51.8 litres, 7.55 kg (Phanteks)
- Motherboards: E-ATX (up to 280 mm wide), ATX, micro ATX, mini ITX; MSI Project Zero, ASUS BTF, Gigabyte Project Stealth
- GPU clearance: 415 mm; CPU cooler: 184 mm
- Radiators: top up to 360 mm, front up to 240 mm, rear 120 mm
- Fans included: 4 x M25-140 D-RGB; mounts for 10 x 120 mm
- Front I/O: 1 x USB-C 3.2 Gen 2, 1 x USB 3.0, audio combo
- Power supply: ATX up to 270 mm
The Phanteks XT Pro Ultra costs £76.99 on Amazon UK at the time of writing (October 2026) with four M25-140 D-RGB fans, or £19.25 per fan, the lowest cost per included fan in this guide. The lighting runs from a built-in controller without software, and Phanteks backs the case with a 5-year limited warranty.
The clearances beat the Lancool 217 and the North, which cost £33.00 and £43.00 more: 415 mm for graphics cards, 184 mm for air coolers, the highest of the five, and room for E-ATX boards up to 280 mm wide and rear-connector boards. The compromises are a 240 mm limit on front radiators and two front USB ports rather than three. For a first build on a budget, see Build vs buy a gaming PC UK 2026.

Which mid tower has the most clearance and cooling?
The Corsair FRAME 4000D RS ARGB has the most graphics card room at 430 mm and the most radiator positions, and the Phanteks XT Pro Ultra has the most cooler room at 184 mm and the cheapest included fans at £19.25 each. The Fractal Design North has the least room on both counts.
| Case | Price | GPU length | Cooler height | Max radiator | Fans included | £ per fan |
|---|---|---|---|---|---|---|
| Lian Li Lancool 217 | £109.99 | 380 mm | 180 mm | 360 mm (top) | 5 | £22.00 |
| NZXT H6 Flow | £84.98 | 365 mm | 163 mm | 360 mm (top) | 3 | £28.33 |
| Corsair FRAME 4000D RS ARGB | £89.99 | 430 mm | 170 mm | 360 mm (front, top, side) | 3 | £30.00 |
| Fractal Design North | £119.99 | 355 mm | 145 mm | 360 mm (front) | 2 | £60.00 |
| Phanteks XT Pro Ultra | £76.99 | 415 mm | 184 mm | 360 mm (top) | 4 | £19.25 |
Price per included fan is the Amazon UK price divided by the fans in the box; it shows how much of the price goes on cooling the buyer would otherwise add. A pack of five ARCTIC P12 PWM PST 120 mm fans costs £42.80 on Amazon UK at the time of writing (October 2026), which is the cost of filling a fan-light case.
Will an RTX 5090 fit in a mid tower case?
Yes: four of the five mid towers here fit both the GeForce RTX 5090 Founders Edition and a large partner card. NVIDIA lists the Founders Edition at 304 mm long and two slots thick; ASUS lists the ROG Astral RTX 5090 at 357.6 mm long and 3.8 slots thick. The Fractal Design North fits the Founders Edition only, and not with a 360 mm front radiator.
| Case | GPU clearance | RTX 5090 Founders Edition (304 mm) | ROG Astral RTX 5090 (357.6 mm) |
|---|---|---|---|
| Corsair FRAME 4000D RS ARGB | 430 mm | 126 mm spare | 72.4 mm spare |
| Phanteks XT Pro Ultra | 415 mm | 111 mm spare | 57.4 mm spare |
| Lian Li Lancool 217 | 380 mm | 76 mm spare | 22.4 mm spare |
| NZXT H6 Flow | 365 mm | 61 mm spare | 7.4 mm spare |
| Fractal Design North | 355 mm | 51 mm spare | Does not fit (2.6 mm short) |
| Fractal Design North, 360 mm front radiator | 300 mm | Does not fit (4 mm short) | Does not fit |
Length is not the only check. NVIDIA recommends a 1,000 W power supply for the RTX 5090, so the power supply length limit matters: 200 mm in the NZXT H6 Flow and 220 mm in the Lian Li Lancool 217. Card picks for every budget are in Best graphics card UK 2026, and builds that need more than a mid tower are covered in Best full tower PC case UK 2026.
Which mid tower case is best for which build?
The build decides the case: the graphics card length, the cooler type and the motherboard standard rule cases in or out before looks or price.
| Build | Pick | Why |
|---|---|---|
| First gaming PC, air cooler, tight budget | Phanteks XT Pro Ultra | Four fans and 184 mm cooler clearance for £76.99 |
| RTX 5090 partner card with a 360 mm AIO | Corsair FRAME 4000D RS ARGB | 430 mm GPU clearance and two 360 mm radiators at once |
| Back-connect board (ASUS BTF, MSI Project Zero) | Corsair FRAME 4000D RS ARGB or Phanteks XT Pro Ultra | Both list all three back-connect standards |
| Most airflow out of the box | Lian Li Lancool 217 | Five fans, two of them 170 mm |
| Glass showcase with an ATX board | NZXT H6 Flow | Dual chamber, panoramic glass, 415 mm tall |
| Living room PC, mid-range graphics card | Fractal Design North | Walnut front, 42 litres, 355 mm GPU limit |
Back-connect boards need a matching case; the boards themselves are ranked in Best motherboard for gaming UK 2026.
Verdict
The Lian Li Lancool 217 at £109.99 is the best mid tower PC case in the UK: five fans, 380 mm of GPU clearance, 180 mm for coolers and back-connect support. The Phanteks XT Pro Ultra at £76.99 is the value pick, and the Corsair FRAME 4000D RS ARGB at £89.99 is the case for the biggest graphics cards and radiators. The NZXT H6 Flow at £84.98 is the dual-chamber showcase, and the Fractal Design North at £119.99 is the one to buy for looks, provided the cooler is under 145 mm.
Every size class, from mini ITX to full tower, is ranked in Best PC case UK 2026.
Frequently asked questions
What is the best mid tower PC case in the UK?
The Lian Li Lancool 217 is the best mid tower PC case in the UK, at £109.99 on Amazon UK at the time of writing (October 2026). Lian Li fits five fans, including two 170 mm front intakes, and lists 380 mm of GPU clearance, 180 mm of CPU cooler clearance and back-connect motherboard support. The Phanteks XT Pro Ultra at £76.99 is the value pick with four 140 mm fans.
What is the best airflow PC case?
The Lian Li Lancool 217 is the best airflow mid tower for most builds: it ships with five fans, two of them 170 mm front intakes, behind a mesh front. The Phanteks XT Pro Ultra ships with four 140 mm D-RGB fans for £76.99 on Amazon UK in October 2026, the lowest cost per included fan in this guide at £19.25. Both clear tall air coolers, at 180 mm and 184 mm.
Will an RTX 5090 fit in a mid tower case?
Yes, in most current mid towers. NVIDIA lists the GeForce RTX 5090 Founders Edition at 304 mm long, and ASUS lists the ROG Astral RTX 5090 at 357.6 mm. The Corsair FRAME 4000D RS ARGB (430 mm), Phanteks XT Pro Ultra (415 mm) and Lian Li Lancool 217 (380 mm) clear both cards. The Fractal Design North (355 mm) fits the Founders Edition only.
Is a dual-chamber PC case worth it?
A dual-chamber case is worth it for glass showcase builds. Moving the power supply and spare cables behind the motherboard tray leaves the glass side clean. The NZXT H6 Flow is the best dual-chamber mid tower at £84.98 on Amazon UK in October 2026, with three pre-installed 120 mm intake fans, 365 mm of GPU clearance and a 360 mm top radiator mount.
Which mid tower cases support back-connect motherboards?
The Corsair FRAME 4000D RS ARGB and Phanteks XT Pro Ultra list support for ASUS BTF, MSI Project Zero and Gigabyte Project Stealth boards, which move the power and data connectors to the back of the motherboard. Lian Li lists back-connect ATX and micro ATX support for the Lancool 217. NZXT lists none for the H6 Flow.
How many fans does a mid tower case need?
Three fans is a practical minimum for a gaming PC: front intakes plus one rear exhaust. The Lian Li Lancool 217 ships with five fans and the Phanteks XT Pro Ultra with four, so neither needs more. The Fractal Design North ships with two 140 mm Aspect fans, so it suits buyers who plan to add a third; the NZXT H6 Flow and Corsair FRAME 4000D RS ARGB ship with three.
Is the Fractal Design North worth it?
The Fractal Design North is worth it for buyers who want a PC that sits in a living room like furniture, at £119.99 on Amazon UK in October 2026. The walnut slat front and 42-litre body are its strengths. Clearance is the trade-off: Fractal lists 145 mm for CPU coolers and 355 mm for graphics cards, or 300 mm with a 360 mm front radiator fitted.
What is the difference between a mid tower and a full tower case?
Size and capacity, though the labels overlap. The mid towers in this guide measure 42 to 57.7 litres. The Phanteks NV7 full tower measures 253 x 532 x 586 mm, about 79 litres, and weighs 16.9 kg. Full towers add 420 mm and 480 mm radiator mounts, but a mid tower such as the Corsair FRAME 4000D RS ARGB already clears a 430 mm graphics card.
