i dont have any specific examples for you. but check out www.tigerdirect.com
they have many many cases and alot of the prices are around 40 bucks or so. last time i built a comp i think i got one here. these will come with power supply too and if you want you can get the cut out sides with neon lights inside. if i was buying a case right now, i would buy from there. there may be better deals out there though... i dunno.
