The machine I'm using to run MythTV is dying. I believe it is a motherboard issue so I've found a replacement.

The current motherboard is an ECS K7S5A (hey it has lasted me 5 years so I got lucky).
The proc is an XP1800+
I'm running FC5.
I've got an Hauppauge PVR 350, Nvidia GF4 video, 2 harddrives (Seagate 150GB, 250GB, both PATA) and a Sony DVD burner that I plan on continuing to use.

What sort of issues should I expect if I switch to a ASRock K7VM3?

Since I'm using onboard sound, I'm guessing that may need some tweaking when I switch, but what else should I expect?

Thank you for any advice you can give.
