I've built a dedicated machine around an Athlon-XP 2600+, 512MB, 200GB.
It works great.

I just stay with mpeg2.  Yea, it uses more disk space, but the quality
is excellent.

IMHO, yes.  Note that in order to use the -350 you MUST store
in MPEG2.  You cannot play out MPEG4 or RTjpeg out the -350 output.
However, the load of myth using the -350 is nearly zero!  It's
spending all it's time on I/O, the CPU isn't doing anything.

I would highly recommend the PVR-x50 cards...  If you can afford them.
