GMC (not to be confused with General Motors) is a relatively new company to the U.S. market, but have been producing quality computer products in South Korea for some time now. They have several innovative HTPC cases, and one of their latest is the Noblesse AVC-S7 Home Theater PC Case. This slimline case incorporates alot of pre-installed hardware into its chasis, so it can alsmost be considered a barebone PC kit... all that's needed is your motherboard (with CPU and memory) and a hard drive.
