actual models i dont know, but here are things to look for in case
1) look for a screwless case, or a case that is easy to open without tools... mine just has the one screw in the back, but it doesn't require a screwdriver u just turn it by hand
2) i hate plastic except for the front, u want a non-bendable metal
3) spots for case fans always welcome
4) when installing the hard drive make sure it's not too close to that speaker... it's a powerful little magnet you know!
5) 300watts of power or more!
6) make sure u get the right drive bay you want, I like mounting brackets myself but many prefer traditional screws
7) u often get what u pay for
