[CentOS] Via Eden

I've been thinking of using one of these for a home theater head unit.

Was planning to configure it with the following:

Dual 4gig compact flash cards w/IDE adapters (about $50/each)
Re-use old 3Ware dual port IDE card to make this a bootable RAID0 array 
(for speed)
Cheap 2.5" 20gig drive for swap and /var partitions
Some sort of remote control (haven't sorted this yet)

The system has hardware mpeg 2/4 acceleration and DVI/Component video 
outputs and SPDIF out for audio.  It will grab the actual content off a 
2TB array that's hiding in another room via ethernet.  On the software 
front, I'm looking at Freevo + Centos.  I'm hoping to get it all 
together for about US$700 in some sort of non-eyesore enclosure for my 
AV rack.

Cheers,
