Well, I was gonna use one of our other old cases, since the case I have it in now had my previous setup in it, but that didn't have enough space for even two of the hard drives I wanted to put in it. I had considered putting it in my previous case from my prior desktop before that, but that case is a monster and uses a ton of fans for the cooling. I may use that monster eventually, since its only from 2003, but I'll probably use it after I move out, since I have no realistic place to put it without losing some mobility in my room. I currently use that kinda like an extra end table, and it sits in a corner of my room that is blocked off by a couple more cases that I have that I was going to eventually turn into physical machines.
A place near me (MicroCenter) has 1.5TB HDDs going for $90, and 1TB HDDs going for $70. (b'-')b
