Case and/or DVD-ROM drive

I would like a standard ATX case with or without power supply. I have several old PS/1 style cases, but the motherboard is I've got is modern type. I'm trying to build a better DVD/SVCD player. My current one is a bit underpowered (300 MHz).

Heck, if anyone has an unused DVD player that also does SVCD, that would solve the problem even simpler.
