Thermals and noise are your biggest concern.
Shuttle and Epia have good offerings. Oscar's also on the right track about the All-in-Wonder if cable tv tuning is desired.
Otherwise, the newer ATI and Nvidia cards (ATI for sure) do HDTV/component-out with the right adapter for the DVI or VGA port on the video card. Some cards come with this, especially third-party manufacturers, some don't and ATI offers it as a buyable item on their website that I recall.
WiFi is fine for Internet connectivity, just make sure you lock it down ;)
Wireless KB/mouse are a lock for this, but you might find mousing a pain unless it's beside you on an end table or something.
Check http://www.ncix.com for some case ideas. Stick with Asus or MSI if you can for motherboards. Samsung value RAM ought to be fine as well.
SATA hard drives make sense because of the minimalist cabling requirements vs PATA. Go with a braided / sheathed cable for the DVD ROM/RW to improve airflow.
Airflow really is king for these systems... picking a case that has the right amount of heat evacuation capability is the most important choice you'll make for this new build.
EDIT - that Shuttle Oscar posted is a great starting point. I'd put a Venice 3200+ in there, a decent DVD ROM (as you already have a PVR), 1GB RAM in dual-channel mode and a half-decent video card (X800XL, etc).
