I’ve written a review on Street Tech of the Ultra 3.5″ hard drive enclosure that TigerDirect is selling for under $20. I knew rolling your own external HD was easy, but it’s mindlessly simple, and you can save some money. For instance, TigerDirect sells an 80GB Ultra drive (a WD HD in an Ultra case) for $90. You can buy the same drive for $45 and the case for $20, saving yourself $25 for less than five minutes work. Or you most likely have an HD in an old computer you can yank, re-case, and use as an external backup drive. That’s what I’m doing.
