From the review:
In our opinion Thermaltake Max 4 Active Cooling is one of the best HDD enclosures available in the market today. It provides both eSATA and USB 2.0 connections, allowing your hard drive to achieve the same performance as if it were installed inside the PC and at the same time having the flexibility of allowing you to connect it to a USB 2.0 port if the computer you are trying to connect it to (at a friend’s home, for example) doesn’t have an eSATA port and you can’t open it to install the SATA-to-eSATA bracket.

This enclosure was also fully compatible with the eSATA on-board connector provided by our ASUS P5K-E/WiFi-AP motherboard. Since some users are complaining about compatibility issues between eSATA enclosures and on-board eSATA ports, this is terrific news.

The material this enclosure uses is the best – aluminum – and it also has an 80-mm fan to cool down your hard drive.

Max 4 Active Cooling price is perfect for a product with this performance and features.
