So this is the HTPC that is planned at the moment:
Using Xlobby, the dragon skin, and numerous plugins...
Storage:
1.5TB (currently) soon to expand to 2TB eventually to go to 4TB at least, 8 IDE devices (via controller card), going to be upgrading to an SATA compliant MB which will allow 4 sata drives on top of that, cooled and with the power supply upped.
DVDs are archives at full quality (with the exception of a few older movies and animated tv shows which I dropped the quality a tad with), ripped with DVDFab to keep menus intact.
CPU/etc:
Going to P4 3.x GHz, 1GB RAM to start.
Currently I'm decoding on an older box with a HW decoder card.
Will be upconverting with FFDShow and MPC after the upgrade.
Planning on putting in a MyHD MDP-130 tuner/capture card.
Output to:
37-42" HDTV
Surround sound receiver
Possibly some high-end Paradigm speakers as I know someone who works there
Any suggestions? I'm mostly all about storage space and having my entire library on HDs with menus. HD's are easy for me to slap in as I already had a ton of space. The PVR feature with the MyHD is basically an afterthought, but it should support unencrypted QAM. Good enough.
