I recently bought a case and so on for a home server, partially prompted by the recent RAID 5 thread on here ...
I ended up getting a
Lian Li 6070. this has room for 4 3.5 HD's inthe bottom, cooled, in a vertical placement, for better access/airflow.
It's also sound-proofed, and I honestly can't tell when it's on or not any more.
Probably the best £100 or so I'ev ever spent on a case.
There are a bunch of reviews of it wandering around on the web too.
I ended up using a Promise SATA RAID5 card as well, but I use it under Windows 2003, so I've no idea if it has Linux drivers or not. The windows software is a little hokey.
Cheers,
Paul.
