I had a hard time finding a case with a power supply on its side which would have been more ideal, but then I came across this case which boasted that you could mount TWO POWER SUPPLIES! The dimension sheet says the top PSU mount is about 40mm taller than the bottom which helps. It really only needs like 1/8" to fit luckily you can cut out the radiator mount and not hurt the rigidity of the case and it has a nice big plastic top to it to cover it.
The giant 92mm fans are just overkill...
My only real complaint is lack of front mount bays and hard drive bays, but it does have enough to fit a floppy emulator and a DVD rom / Cd burner which I will need as this machine will be used to store all my DVD's as a home media server until I can afford a nice 32TB nas. I added a PCI sata card so I can use more modern hard drives, but I guess I'll find out the hard way what size limits the hardware / windows 2000 will have. I also went to a ISA sound card as I had them and all the PCI slots will be full once I add a USB card. Also sound will not be used much as it's server, but why not add hardware I have in my collection?
The case didnt have a PC speaker... good think I had one from some old case to use for debug
