No idea on this one, but these two work fine:
http://www.pcmicrostore.com/PartDetail.aspx?q=b:1499;c:36232;p:10501345
Hotway 3.5" USB 2/FW aluminum 3.5" enclosure $38
ByteCC 5.25" enclosure that takes 3.5" drives

Usuall $40-45 most everywhere.

Both work fine with various HDs over both USB & FW connectors, are easy
to install, require no drivers and dont' overheat the drives.
The ByteCC model has lots of room inside along with a rear fan to keep
the drive cooler than the Hotway, but the Hotway never gets so hot you'd
kill a drive either. (Only very hot, similar to if you had it on a desk
bare.)
The ByteCC runs louder due to the fan; the Hotway is as quite as your
HD. Standard AC cable on the ByteCC; external adapter on the Hotway.
Either have been great buys for me, and I would pick either no problem.
Prefer the Hotway right now because it's more portable and quieter.
