Cooler Master Cosmos C700P

The best full-tower PC case

Physically controlled RGB.
Universal, multi-orientation design.




Form factor: Full-tower | Dimensions: 639 x 306 x 651mm (L x W x H; 25.2 x 12 x 25.6 inches) | Mobo compatibility: Mini-ITX, Micro ATX, ATX, E-ATX (12 x 11 inches) | PSU support: Bottom mount, ATX PS2 | I/O: USB 3.1 Gen 2 Type-C x 1, USB 3.0 x 4, fan speed and RGB control buttons, audio in/out (supports HD Audio) | Includes: 2 x 140mm front fans, 1 x 140mm rear fan

The Cooler Master Cosmos C700P desktop computer case portability is not one of its forte. This 22kg (or 48.5 lbs) behemoth isn’t exactly the most lightweight case on the block. Don’t take the lack of portability to mean that the Cosmos C700P isn’t a great case, it is, but it just means that, if you want to carry it around, you’ll have to take advantage of the upper rails. Still, despite its thickness, the C700P is flexible and beautiful, thanks to Cooler Master’s decision to implement full RGB lighting and support for six different system orientations.

Form factor: Mid-tower | Dimensions: 492 x 201 x 433mm (L x W x H; 19.4 x 7.9 x 17 inches) | PSU support: ATX | I/O: 1 x USB 3.0, 1 x USB 2.0, 1 x headphone port, 1 x microphone port, power on button, reset button | Includes: 1 x 120mm LED front fan

Even if you’re trying to avoid spending a fortune on your build, it’s probably not a great idea to not settle for the absolute cheapest PC case you can find. For the most part, cheap cases don’t really incorporate proper ventilation and airflow, not to mention you’ll end up buying your own fans and cable management supplies. The Corsair Carbide Spec-04, on the other hand, shows up even some of the more expensive cases. It does so with rubberized feet, an included LED fan and tons of room to spare for additional fans and components.

The case is similar to the phenomenally popular Corsair 100R and 200R cases, but was designed for the microATX crowd that doesn’t want to spend a ton of money. The Carbide Series 88R microATX mid tower has all the modern features you need; 4 expansion slots, front panel USB 3.0 header, room for a five 120mm fans (2 front, 2 top and 1 rear), storage drive space for two traditional 3.5″ hard drives and two 2.5″ SSDs is available as well as a front accessible 5.25″ drive bay. The case measures in at 440mm x 198mm x 378mm and can fit both Mini-ITX and MicroATX motherboards. The case is fairly small, but can still fit video cards that are up to 383mm in length, 160mm long power supplies and CPU coolers that are 150mm in height.

NZXT White H200i Smart Mini ITX Windowed PC Gaming Case

Adaptive noise reduction.

Form factor: Small form factor | Dimensions: 210 x 349 x 372mm (L x W x H; 8.3 x 13.7 x 14.6 inches) | Mobo compatibility: Mini-ITX | PSU support: ATX | I/O: 2 x USB 3.1 Gen 1, 1 x audio/mic, 3 x fan channels with max 10W per channel output, 1 x RGB LED port support up to 4 x HUE + LED strips or 5 x Aer RGB fans | Includes: 1 x Aer F120 Case Version top fan, 1 x Aer F120 Case Version rear fan

It has taken some time but this hot small form factor has finally made it way into the NZXT new H range of cases. I wouldn’t come as a surprise as the Mini-ITX form factor is gaining popularity amongst the modding community. NZXT has managed to cram in a lot of the same features as its micro ATX and mid tower equivalents, with mesmerising, built-in and Smart Device-controlled RGB lighting and an adaptive noise sensor that sees improvement only by way of the Grid+ V3 fan controller.

Great airflow.

Slightly larger than other mid towers.


Form factor: Mid-tower | Dimensions: 544 x 242 x 542mm (L x W x H; 21.4 x 9.5 x 21.3 inches) | Mobo compatibility: Mini-ITX, Micro ATX, ATX, E-ATX (12 x 10.7 inches) | PSU support: Bottom mount, ATX PS2 | I/O: USB 3.0 x2, USB 2.0 x2, Audio in & out (supports HD audio) | Includes: 2x 200 x 25mm RGB fan, 1x 140 x 25mm fan

Cooler Master has made a name for itself for, well, cooling – and the Cooler Master H500P Mesh is further evidence of just how cool they are. The H500P has plenty of space for airflow, even accommodating up to 360mm radiators on the top and front for when you really want to take your cooling to the next level. Add on top of that the RGB lighting and tempered glass side panel and you have the potential to build something beautiful with this case. You should do it.
