That thing costs more then the $1500 goal price (notice he doesn't include the price of Windows 7, at least another $120 for just the OEM) which isn't fairly inexpensive to me for a transport/source. It doesn't seem to be all too great either, I thought the power supply choice of a switch brick to be fairly horrid. I wouldn't have gone with a USB CD-Rom either. Good choices on keeping it silent and support all those bit rates, but I can't imagine it sounds much better then most other HTPCs if you were to add in the sound card alone.
Actually, I wouldn't use a computer as a source like this. With that kind of loot, I'd probably reach a little further and try to buy a used Cary 306 SACD with digital input and m2tech hiface with my computer and feel more secure.
