I don't know much about any of these systems, but Costco does have some Western Digital products at decent prices. This is the one (www.costco.com) Travis and I were looking at, but they have some fancier versions (www.costco.com)as well. Again, I don't know much about these and I'm sure the advice from Kaiden and Conrad is much more helpful, but I thought I'd throw in what I'd seen recently.
