GMC is a Korean based company who focus almost entirely on the design and production of HTPC cases. We had a look at several of their products in the past, each of them designed with a different purpose in mind. Today we will take a look at their latest HTPC case, the AVC-S7. The AVC-S7 is an elegant but very short case which is designed to match DVD players and other home theater equipment. Let us see if such a short case can be practical for housing modern home theater systems.
