There's two ways to go about a HTPC of this magnitude.
1) The silent minimalist build (so practically no 3D gaming at all, just movies/TV), with the server located else where. It'll be just another flat piece of appliance under the cabinet. This is more suitable for multiple HTPCs in home and a more professional approach. My HTPC is a good example of that. The potential with this setup is endless if you work in the field of IT and know how to make most use of the server.
2) A full-out setup using mATX or ATX plus a full height case (more going the direction of cube like Silverstone Sugo range) which is required for high-end 3D gaming. The downside with this setup is it's almost a full PC in your living room, making it bearable (appearance, noise, efficiency..etc.) will require a relatively high budget which $1428 is enough.
As expected most people on XCPUS tend to go with option #2. It's just not my cup of tea when it comes to HTPC.
Looking at your requirement, you could scrape through with i5 650 mATX plus a low-profile HD5670 (coming very soon). That's about the most 3D power currently masterable with option #1.
