While most market headlines are given to the latest and greatest processors focusing on speed and performance, there exists a sub-market focused on squeezing as much technology as possible into the smallest footprint.  Based around the Mini-ITX and smaller motherboards, this sub-market was slow to grow until the explosion of the idea for an HTPC brought a wide-spread desire to make useful media computers that would blend well with other media components.  To appeal to this market, ThermalTake introduced the SD100, a slick looking Mini-ITX home theater case that would be right at home next to a PS3 or home theater system.  Let's begin with a review of the case specifications, then move on to first impressions.
