Antec MX-1 Actively Cooled HDD Enclosure
 

The Antec MX-1 is not your run-of-the-mill enclosure. Most enclosures are all metal and don't include a fan or even a stand. The MX-1 is extremely lightweight and quieter than most enclosures I have used in the past. The option of using either USB or eSATA is a nice touch and keeps the MX-1 flexible while on the go.
