Thanks for the reply. Actually, the ASUS "does" have SPDIF out..
From AUDIO section of Specs for the MB:ADI AD1986A High Difinition Audio 5.1channel CODEC
Support Jack-Sensing and S/PDIF out interface
I'm still torn.....will I overclock??? Also, the ultimate plan is to get an PCI-X video card (DX 10) with HDMI out.. So...am I worried about the on board 6150?? I just want to enjoy my experience while I wait for the DX10 cards...
EDIT: Actually, I guess the ASUS only has the S/PDIF header....That's ok, because the nMediaPC HTPC case I am looking at (280), has the S/PDIF Output Jack on it.
