I have been familiar with Thermaltake products for years, having built my first custom computer using one of their Xaser-II cases. I’m also familiar with their typical over-engineering. In the case of the Xaser-II, the front door was made of ¼-inch cold-rolled steel, and weighed close to five pounds. Throughout the years, that case has served many purposes and held together perfectly due to its stellar build quality. Up now is the BlacX Duet, an external hard drive dock for internal SATA hard drives. The “Duet” is for two drives being simultaneously accessible by eSATA and USB with this product.
