I'm in a bit of a quandary at the moment. I'm going to build a HTPC and use one of the Shuttle barebones (..it's the only on that will fit in the cabinet.) There are two models on the market : SD39P2 : 419 SP35P2 Pro : 391 Putting aside the fancy gadgets (Finger print recognition etc.) the only difference I can se between the SD35 and SD39 is the Intel P35 Express board on the SD35 and the Intel 975X on the SD39. So what would be your recommendation ?
