Zagall still offers this Aluminum USB 2.0 External 2.5" IDE Hard Drive Enclosure in Silver for $3.99 with free shipping. That ties our mention from a week ago as the lowest total price we've seen for an IDE hard drive enclosure. (It's a current low for a comparable item by a buck.) This aluminium enclosure can accept 2.5" hard drives up to 320GB and is compatible with most Mac and PC computers.
