I don't really need a lot of space, and I'm thinking 200g's will be enough, but I'm not entirely sure.
There are two different hard drives I'm looking at right now, a;
Seagate Barracuda 7200RPM 8MB Cache 250Gig
Western Digital Caviar SE 320Gig 7200RPM 8MB Cache
I know one is serial ata and one is ide ultra, but I'm pretty sure I have serial ata -> ide connectors or something, I'm sort of a noob on hard drives so any help would be appriciated.
