THE REV300 INTERIOR

In terms of interior space, the REV300 seems to be doing very well (the lack of rubber grommets however does stand out).

Past the three front 140mm ARGB fans you can mount an 240/280/360/420mm radiator (32mm thickness for the 420mm radiator - no limit for the other sizes).

You can also use an 240/280/360mm radiator at the rear of the REV300 (thickness will depend on your motherboard components and of course the top fan).

Even though the REV300 features a dual chamber design since it's perforated it's mostly to cover cables coming from the PSU (the far left plastic piece can be removed to mount an 420mm radiator).

As mentioned earlier the lack of rubber grommets on the mainboard tray stands out but since you can fit even E-ATX models here i have no complaints really.

All 8 PCI expansion slots are kept in place with typical screws.

Turning the REV300 around we find three vertical drive trays and the 8-port ARGB controller.

All 3 vertical drive trays are made out of aluminum (the small ones can accommodate 2.5" drives whereas the large one can accommodate either 2x2.5" or 2x3.5" drives).

There's also a small drive cage right next to the PSU area which has room for 1x2.5" and 1x3.5" drives.
