I recently bought one of these cases after some research on the internet, I have the 2.5 Drive enclosure as well, but the 3.5" one works as a media reader and 2 port USB Hub on top of my 5 port USB hub, it is quiet and does not get hot, also it has a vertical stand or it will lay down flat. I got mine on ebay for $18 bucks. I installed my 500 GB Seagate in this in roughly 5-7 minutes I was up and running using it for my Time Machine Backups.
