The side panels on 300R are secured in place via 2x thumbscrews on each side. Once removed, the internal layout of this case is revealed. The prominent side has a clean design with various tool-less mechanisms for getting devices in and out of 300R. Around the motherboard tray (which supports mATX and ATX) are cable management cut-outs – these are without the rubber grommets. There is no need to use motherboard stand-offs to get the motherboard installed since the screw holes have been raised up.

Moving in for a closer look at the inside of 300R we first come to the PSU area. This area has a mesh underlay and a dust filter is removable from the rear of the case. Unfortunately the mounts that the PSU sits on have no anti-vibration rubber so the unit could as a consequence cause scratching due to the metal-on-metal. I’d have liked to see some sort of rubber here, however small. There is support for longer PSUs within 300R.

There are 7 PCI expansion slot covers – each come with the ventilation holes and thumbscrews for easy removal. To the side is more ventilation via a honeycomb mesh panel.
