I won't be able to access the machine itself for another two weeks so I can't get that information.

1. I plan on retaining two drives that it's currently using. One is a 160GB and the other is a 300GB. Both of these are IDE drives.

2. I plan on installing some distribution of Linux. I was thinking either Ubuntu or SuSE.

3. Yes.

There's a local shop that are selling the 1TB SATA drives for $30 so I figured it might be a nice time to purchase some more room. That and I have an empty hot-swap bay. Oh so tempting.
