Since the SV24 Shuttle has continued to improve their XPC line and the SS51G has been the most valuable addition to this line since the SV24. Most aspects of the SS51G can be considered to be perfect such as the integration of AGP, the appearance and size of the case or its cooling solution. Either way the SS51G is easily the best value XPC to date and is the first barebone system that can be seen to replace current desktop PC's.
