I just got my hands on a free server. It's a dual PIII with 1 gig memory, four hot swapable HDDs, redundant power supplies, etc...

I want to learn Linux and eventually move some of my websites over to Linux/apache on this new server. I'll probably use it as a test server until I get comfortable with Linux. Can some folks reccomend a good distro to start with. I'm a total Linux newbie so I don't know much of anything about it so I'm also looking for any advice. Thanks!
