We are offering Western Digital Green drives on our website at $49 for 500GB and $69 for 1TB respectively. They can be used in anything that will accept 3.5" SATA drives.

There's a whole bunch of decent hard drive deals on Ebay Deals. I noticed this particular model because I paid around $100 a little while ago and thought I'd done well with that.
