I really like the Antec Performance I P180 Silver ATX Mid Tower Computer Case.

One of the really interesting things Ive seen that you might want to consider is a BTX case. The loud, noisy PSU is farther away from you ears.

Another piece of advice I'd give is to no go crazy with fans and just get as many as you can. Rather, you should try to go for fewer(but higher quality) fans. You really don't want to skimp and be stuck with a noisy fan. Look at Zalman.
