Just opened mine up and took a look at it. I'd recommend looking at the Mad Shrimps review. The hardest part about this thing is cracking it open. You have to pull the front cover forward away from the frame. I think this is a problem in similar cases (In-Win BT611) I didn't realize how small these things are to work in. PSU is an enhance ENP-2220A power supply. As stated before, the pci/agp brackets are half-height. There is a removable tray, to work on all the drives. There is room for a 3.5 floppy disk (I assume you could put a second HD there if you needed), a 3.5 HDD, (under the floppy bay) and a DVD/CD Rom bay (adjacent to floppy drive area). The DVD drive would have to be screwed from the bottom. A bag of standoffs and screws was included, as well as a paper with the USB pin outs (there are 2 front USB ports, spec stated 2.0) and audio pin outs (for mic and headphone jack in the front).
One worry I had was there is plenty of venting holes on the side, but none on the top. Additionally you'd need a low-profile cooler maybe? Again, I'm not a professional, I bought this based on reviews from the web and the price seemed too hot to miss.
As far as the footprint goes. I have a Panasonic receiver XR-55, and it's a little slimmer, but not much than that receiver. DVD player (Phillips DVP5960) is a lot smaller and shorter than this case. I don't think it's a bad purchase for $30 for a desktop case, that can also be converted to a slim-tower case.
