You definitely should get one of these

This is sort of old news for techies but I just recently got one of these hard drive adapters. It takes 2.5 and 3.5 internal hard drives that you can just slide in. Benefit: internal hard drives are ridiculously cheaper (I got a 1TB drive for $100!). The base was about $60. Not a bad one time fee to save a butt load on future hard drives. I'm sure I'll eat through this disk and need another soon. So if you require lots of space, look into one of these.
