The interior of the X-Supra is pretty much like the X-Telstar, with UV-Reactive tool-free devices. There are five 5 ¼” bays, two external 3 ½” bays and three hard drive bays.
The interior is finished well with rolled edges; I found no sharp edges anywhere.
The inside rear is also pretty typical, with a blue LED 120mm fan and the tool-free PCI locks are UV-reactive like the other tool-free locks.
One item inside is rather out of the ordinary… the electronics for the USB, IEEE 1394 and audio are exposed. Probably not an issue, but this is where I usually have a big wad of extra power cables if the PSU I happen to be using at the time isn't modular. A little care should be taken if there are a lot of cables to be hidden here.
