I promised an update nearly three weeks ago and I'm finally getting back to doing it. Part of the delay was due to a bad PSU (power supply). It took some troubleshooting to narrow the problem down to the PSU and then I had to RMA the entire HTPC case since the fan came with the case. Newegg took care of me promptly though so I was back in business within the week.
This new HTPC is being used as a "client HTPC" using BeyondTV Link and Beyond Media. It accesses all of its content from my BeyondTV server PC including live and recorded TV, Video, DVD, Music and other content.
Requirements for this "media" computer:
- The PC had to fit into a "living room" environment. It didn't need to be tiny in size, but it did need to look like it belongs in the entertainment center.
- I needed to handle HD TV watching. I want it to be powerful enough to handle HD with ease. as well as anything else I threw at it
- It needed to be fairly quiet.
I did some research and posted my plans on the snapstream forums. I highly recommend anyone planning to buy or build an HTPC to post their plans on a forum like snapstream, sagetv, avsforums or others to get input from others who have done it before. There are many who have expertise on this subject. These people can many times give you ideas you hadn't thought of, give you advice and save you a bunch of money.

Results
After using this HTPC for several weeks now I can say I'm very happy with the results. You will notice that I don't have a videocard in this machine. Because the motherboard has an Nvidia 6150 integrated video built-in, there was no need for a separate videocard. The integrated video handles HD with ease. I'm using overlay (not 3d for you BTV users) and have extremely smooth video playback. Using the integrated video save a slot on the board, keeps it quiet and doesn't generate the extra heat that comes with many video cards. I should note that I have this PC networked on a gigabit ethernet (integrated into the motherboard) as I think that is always a wise choice when you are streaming HD from one PC to another.

I chose 1GB of memory as that seems to be plenty for the HTPC tasks I'm throwing at it. The processor is also keeping up with its HTPC tasks just fine. For a nice summary of the software I have on this machine, see this post. Thanks to everyone on the snapstream forums for the help on this project and especially cmcquistion as he was the one that recommended the excellent motherboard with integrated video.
Future Plans:
1. Buy a larger flat-screen TV for the room.
2. Move the HTPC and receiver to a nice-looking cabinet (it's currently in a junk cabinet from my college days)
3. Add in-ceiling speakers for surround.
