[mythtv-users] MythTV Frontend upgrade

I'm considering upgrading my MythTV Frontend systems from the very quiet
Shuttle systems to something less dependent upon a video card for HD.
What I have Now:
I've got three shuttle systems each with an AMD64 3000 single core
processor, 1 GB of RAM, a small laptop hard drive, the quiet shuttle
heat-pipe setup, and a 512MB NVIDIA 6200 (AGP) video card.
I've got one backend system just for recordings, and a separate system
serving out 4TB of striped storage containing DVD ISO's. This
filesystem is mounted via NFS to the frontends when playing ISO's.
Due to a bug introduced in the NVIDIA drivers, I can't upgrade from the
100.14.11 release without getting choppy video. 100.14.11 won't compile
on the later kernels, so I am stuck at the kernel that I am at. In
addition, I am seeing pretty frequent choppiness when playing the DVD
ISO's off of the NFS storage.
A test upgrade to the latest kernel (via Fedora 10) cleared up the
choppy playback, but, alas, I had to run a later NVIDIA driver. That
caused the processor load to go to 100% when playing back HD content
which caused that to be choppy.
I'm considering introducing new hardware and selling off what I have. I
was thinking of something like a microATX motherboard with a medium
powered dual-core processor with a minimum of 1GB of RAM and DVI (or
HDMI.. or both) out. However, I'm having a bit of difficulty in finding
a smallish case (one that fits in an entertainment center). Possibly
something similar to

(13inches x 13.5 inches x 5.5 inches), but I am also concerned that
anything like that would have a noisy processor and power supply fan.
I'm a bit spoiled by the Shuttle case (one small fan for the power
supply, and a heat pipe setup to a single case fan for the processor..
which averages around 1000RPM) and was hoping to construct something
I'm at the point where I believe that the price of the hardware has come
down enough such that a dual-core setup would be inexpensive enough to
build powerful enough frontends to drive HD content without the funky
custom nvidia drivers (although, I do not know if this is necessarily true).
Does anyone have any recommendations? Also, frankly, I'm tired of the
Fedora release cycle.. I don't need it for these frontend-only systems
and while it tends to fix some things, it also tends to break other
things (hence, the predicament I am in now). CentOS would be great if it
has the necessary driver support for current hardware and the repo is
reliable (I seem to recall ATrpms's once having CentOS as a beta or test
