A cube-shaped tower takes up less desk than a classic mid-tower and looks tidier on a shelf, which is why the best cube PC cases keep turning up in small-space builds. This guide covers six compact picks. Fair warning: only two are described as cube designs in our source data (Fractal Design Node 804 and Thermaltake The Tower 100, the latter as “cube-like”). The other four are compact micro-ATX or mini-ITX cases that serve the same purpose, and we label them as near-fits. We left out the Cooler Master MasterBox Q500L because major US retailers showed it out of stock.
A quick note on method: we did not run hands-on tests. These picks are based on published specifications and reviewer feedback from sources such as Tom’s Hardware, TechPowerUp, Windows Central and PC Gamer. Prices are approximate ranges, not live-checked, so confirm the current listing before buying.
What to look for in the best cube cases for PC builds
Start with the motherboard. Most compact cubes take micro-ATX or mini-ITX only, so check that before choosing parts. If you want a full-size ATX board, you are looking at a different category, and our data does not list an ATX cube pick.
Next, check GPU length and CPU cooler height. Small cases trade volume for tight clearances, and several below limit cooler height or radiator size. Finally, consider cooling and fans: some cases ship with fans, others with none, which adds to the real cost.
Fractal Design Node 804 – best cube case for storage-heavy builds
The Fractal Design Node 804 is the clearest cube in our data, with a dual-chamber layout. Specs list micro-ATX and ITX support, a 41 L volume, three included Silent Series R2 fans, a built-in fan controller, and a maximum GPU length of 320 mm (290 mm with the HDD cage fitted). Storage is 8x 3.5 in plus 4x 2.5 in, or 10x 3.5 in. Approximate price: 135 to 150 dollars.
Pros: huge drive capacity, three fans included, praised by Windows Central as a DIY NAS case.
Cons: no USB-C (two USB 3.0 ports), an older 2017 design, and one retailer lists it as end of life, so stock is inconsistent.
Best for: storage-heavy or NAS-style builds.
Thermaltake The Tower 100 – best cube-like showcase for mini-ITX
Thermaltake The Tower 100 is a cube-like vertical tower with a 266 x 266 mm footprint and three glass panes. It supports ITX boards, includes two 120 mm fans, fits GPUs up to 330 mm and coolers up to 190 mm, and has front USB-C. Radiator support is 120 mm at the top. Approximate price: 80 to 120 dollars.
Pros: striking showcase look, fans included, several colors.
Cons: Tom’s Hardware and Hardware Asylum say it is tight for hot CPUs and barely fits an AIO; one reseller lists it as end of life.
Best for: a display-style mini-ITX build with a modest CPU.
Jonsbo Z20 – best compact cube-style case with a handle (near-fit)
The Jonsbo / Jonsplus Z20 is a micro-ATX case, not described as a cube in our data, so treat it as a near-fit. Listings show mATX and ITX support, a tempered-glass side, a detachable carrying handle, GPUs up to 363 mm, a 240 mm top radiator, and front USB-C Gen2. Volume is quoted as 20 to 25 L depending on how it is measured. Approximate price: 99 to 105 dollars.
Pros: detachable handle, long-GPU and ATX PSU support in a small body.
Cons: tight interior needing cable planning, and cheaper mATX cases exist, so you pay partly for the look.
Best for: portable LAN-style builds.
Cooler Master NR200P V2 – best small case for a full-size GPU (near-fit)
The Cooler Master NR200P V2 is an ITX small-form-factor case, so it is a near-fit rather than a labeled cube. Specs list 18.25 L, GPUs up to 356 mm with a vertical-mount PCIe 4.0 riser included, a 280 mm top AIO bracket, front USB-C, and both tempered-glass and mesh side panels. Approximate price: 140 to 155 dollars, though sources conflict.
Pros: fits big GPUs, includes both panel types, supports a 280 mm AIO.
Cons: air coolers limited to 67 mm, vertical GPU only.
Best for: compact builds with a full-size graphics card.
HYTE Revolt 3 – best console-style compact tower (near-fit)
The HYTE Revolt 3 is a mini-ITX console-style tower, not a labeled cube. Specs list 18.4 L, a 335 mm triple-slot GPU, a 280 mm AIO, front USB-C, some dust filtering and a retractable carry handle. Approximate price: 100 to 130 dollars.
Pros: handle, full-size GPU room, tool-free panels.
Cons: Basic Tutorials found the handle can wobble and rattle, and it is closer to mATX size than typical ITX. Fan and riser inclusion conflict across sources, so check before buying.
Best for: a portable build with a big GPU.
Thermaltake The Tower 300 – best colorful micro-ATX showcase (near-fit)
Thermaltake The Tower 300 is an octagonal micro-ATX showcase with three glass panels, so it is a near-fit. Listings show two 140 mm top fans and several colors, with GPU length and radiator limits that conflict between sources (400 versus 360 mm GPU, 420 versus 360 mm radiator). Approximate price: 150 to 170 dollars.
Pros: many color options, glass showcase look.
Cons: micro-ATX only, pricey for its size, spotty stock.
Best for: colorful display builds.
FAQ about the best cube style gaming PC cases
Are there modular cube PC cases?
Our data does not label any of these as modular. The Node 804 splits into two chambers, which gives a similar flexibility for drives, but we make no wider modularity claim.
Can I use an ATX board in a cube case?
Not in any pick here. They support micro-ATX or mini-ITX, so an ATX cube would need a different case.
Is a cube case good for gaming?
It can be, if you check GPU length and cooler height first. Reviewers flag tight CPU clearance on the Tower 100, and the Node 804 limits GPU length with the drive cage installed.
Which is the best cube case for PC storage?
Based on specs, the Fractal Design Node 804, thanks to up to 10x 3.5 in drive capacity.
