MATX Love – Corsair 2800X RS-R ARGB PC Case Review
Meet the Corsair 2800 RS-R ARGB
Corsair gives the Micro-ATX form factor some love with its 2800X RS-R ARGB PC case
Corsair has given the Micro ATX (MATX) form factor a boost with its newest PC case, the 2800X RS-R ARGB. This PC case targets two things: affordability and Micro ATX. It’s really that simple.
At its essence, this case is a Micro ATX version of the Corsair 3500X (see our review here). The 2800X retains the case’s panoramic glass design with front and side tempered glass panels, and is notably shorter than the 3500X (447mm vs 506mm). Like all modern Corsair PC cases, the 2800X supports back-connect motherboards (ASUS BTF, MSI Project Zero, Gigabyte Project Stealth etc).
Support for large GPUs, with some caveats
We managed to fit a Sapphire Radeon RX 9070 XT Nitro+ graphics card inside this case. This GPU is a 3.2-slot graphics card that is 330.8mm long. As you can see, this PC case can fit longer graphics cards. That said, this GPU configuration leaves users with minimal space under their graphics card. Certainly not enough to use the 2800X’s OSU shroud fan mounts.
Note that our chosen motherboard does not have a PCIe slot that utilises this case’s top PCIe slot. If your motherboard places its top PCIe slot higher, this case can support even 4-slot graphics cards. Alternatively, if you use a standard 2-slot GPU, this PCIe slot configuration would allow users to mount two 120mm fans on this case’s PSU shroud. With MATX, the positioning of motherboard PCIe slots matters.
Cooling options
Included with this case are three Corsair RX120-R reverse-blade fans. All three of these fans act as intakes. Unlike other Corsair PC cases, the 2800X is not available without fans, or with a premium iCUE fan setup. Buyers of this case only have two options: Black or White.
At the top of the 2800X, users can install up to three 120mm fans or two 140mm fans. The case also supports a 280mm or 360mm liquid-cooling radiator. While the side of this case supports three 120mm fans, this area can only accommodate a 240mm liquid-cooling radiator.
The rear of the 2800X can support a single 120mm fan, and the case’s PSU shroud can support up to two 120mm fans. As mentioned before, these fan mounts can only be used when a thinner GPU is used inside the 2800X.
Specifications
At its core, the 2800X is a shortened version of a full-sized ATX case. As such, this PC case isn’t much smaller than a standard ATX PC case. Yes, it is more compact, but not by much. If you want to max out your GPU size, this PC case supports GPUs up to 410mm long. The case also supports CPU coolers up to 170mm high. That’s just enough to fit a Noctua NH-D15 G2 CPU cooler with millimeters to spare.
PSU-wise, this case supports standard ATX PSUs, citing no maximum PSU length. This implies that Corsair does not foresee any PSU compatibility issues with this PC case. Additionally, Corsair states that this case offers 24mm of cable routing space. We confirmed this with our own measurements.
Pricing
At £69.99, this PC case is a bargain. With three reverse-blade fans and two larger tempered glass windows included, it’s hard to argue with Corsair’s value proposition here. In the US, this case will cost $89.99, and in Europe it will cost €79.90 Euros. Solid pricing for a new PC case with this aesthetic.
