For most of my computers I use old cases from obsolete computers that were given to me or I got at a computer repair place in the form of a old computer with a slow mobo and slow processor. Some of these were fairly nice with plenty of room and either didn't cost me a dime or cost < $25. I just removed the old guts and put in the new. Just depends on how fancy a case you want, I guess.
I have 4 hard drives and 2 dvd drives. I need to add more hard drives but have no more room. I dont want to spend a lot and I already have a really nice PSU I got on sale 110 from 130 on newegg, so any case that comes with a psu is a waste. And all the full towers I see are >$70. Any ideas on some sort of ghetto riging? Or way to make my own case?
