Found this combo out on Newegg as well. We're I in the market, I'd definitely consider it:Newegg HTPC Combo
Add in Windows 7 Home Premium and a CPU Heatsink/Fan and you're only around $650. Add in a Ceton Tuner Card
, which should be available by the time you're ready to build and that puts you just over $1K.
The motherboard in this combo provides you with HDMI out and an HD4200 integrated graphics chipset, so no need for a discrete graphics card. The motherboard also has an Optical S/PDIF audio output for connecting to a surround sound receiver.
My only real concern with this setup would be finding a CPU HSF that's going to work inside that case.
