Do yourself a favor and pick up a cheap DVD burner. You'll want a DVD burner because you will probably want to backup important sessions to DVDs. Backing up to cd takes much much longer and is a total waste of time.

Many sample cds use DVDs. So if you don't have a DVD reader, you are screwed!

I'm using the same Toshiba DVD burner I bought 4 years ago. It does fine.

Monitor, Keyboard, Mouse, Etc

Don't forget to pick up this kind of stuff too. Picking up a keyboard and a mouse is usually super cheap online. I think I paid $5 for my keyboard and $5 for my mouse from newegg.
