Well in that case I stand corrected! I think you'll be very happy with this. The only other possible cost saving advice I can give is that if you are only going to be using this for HTPC (read, non-gaming) and are not going to be doing on-the-fly transcoding, you could get a cheaper processor. If you're near a microcenter, they have the G630 for $50.
Also for OTA tuner, keep an eye out for deals on the Silicon Dust HDHomeRun. Woot often has the prime for less than $150 if you need CableCARD support. I have a dual for OTA only and I've been very happy with it.
