Anandtech has a preview/review of Shuttle's upcoming HTPC. I think it looks terrific, particularly with the creative audio chip with the spdif out as well as component, dvi, and svideo all available. I just hope that there is some alternate configurations available, or perhaps just the barebones sometime down the line.
