So, maybe it's time to split my frontend away from the backend? So, if that's the case, what's the tiniest frontend I can make that will still play DVDs without stuttering?

Quickest route would be to put an SP13000 motherboard in it, and switch
to using the Sp's video instead of the PVR350's video out. You still get
an S-video output for the TV.
The via driver is pretty good already, and the openchrome guys have got
xvmc figured out pretty well.
I can fastforward a program being played at 3x, 5x, 10x or 20x while
recording three other streams (PVR500 + HD3000).
Rewind is still weird and jumpy but it works.
Power requirement is down a little too. I have no heat problems in a
SilverStoneTek LC11M case, using the minimal sized heatsink+ 40mm CPU
fan and an 80mm side fan for heat extraction. That combo is aided by a
folded cardboard channel which pulls air from the area of the PCI slot,
across the southbridge, and CPU to the side extraction fan.
Are you sure that the heat problem is actually caused by the
motherboard? Maybe your power supply is the problem? Try an external
brick to power things? The slight whisper I hear from my box now is the
sound of the P.S. fan, now that the blades are dirty from 18 months of
You could/should change the PVR350 for a PVR500. That will give you 2
tuners in the space of one. And the SP has onboard handling for digital
streams if you attach an HDHomeRun.
Can't do anything about space for more drives unless you want to change
your case. I recommend the SilverstoneTek LC line. Or just get a bigger
drive. With 250G SATA no available at not much over $100, it seems silly
to stint on it. (The Silverstone LC11 will take 2 3.5" drives easily and
there actually is space for a third, but really hard to reach and
The newer EX line of boards uses the CN700 series chipset and as far as
I can see, the opnechrome driver does not, yet, have the bugs worked out.
