Selling my gently used (only for about 4 months) HTPC. Was built as a labor of love, but then I deployed and wife didn't want to operate it in my absence so it fell by the wayside as we settled on a Roku for her and the kids.
In my experimenting I successfully ran:
Windows Media Center w/ direct record to the 2TB HD from OTA & CableCard
MythBuntu w/ direct record to the 2TB HD from OTA & CableCard
