Ask HN: External hard drive enclosures... Recommendations?

I have 3 spare 3.5" SATA hard drives (2 x 160GB and 1x 120GB). I'm looking for recommendations either on an external enclosure that supports 3 or 4 drives, or a cheap enclosure that I can by 3 of. Preferably I'd go for the first option unless it is prohibitively expensive.

I have heard horror stories about some external enclosures conducting electricity and giving shocks to people if they touch them in the wrong place and other stories of them failing in other less spectacular but still annoying ways. I would like to avoid this by getting something that is good quality.
