GAR - I had a nice long post in reply and... lost the contents. Okay, the short, short version:
Yes, there are a lot of cases with the same basic layout such as ones made by Athenatech, Powmax, etc. However, mine is made of aluminum.
Entire case from front to back is 14.5". Not counting the plastic face, 13". From the end of the 3½" drive bays to the back, 8". The HDD sits on a slide out tray which sticks out ½" beyond the drive bays, so 7.5" from the tray to back of case. The HDD sticks out even more, so from back of installed HDD to back of case is 6.75", and that's not counting room for cabling.
The newest versions of the Enermax 270W SFX PSU puts out 20A on +12v. The Fortron 300W SFX PSU that I have in my other, identical case has dual rails with 8A and 14.5A. Both run about $40 or so and have 20+4 pin power for motherboard, but no PCI-E 6 pin. They are a good choice for all but a massively overpowered machine.
