Install advice

[wvroger]

I'm looking to deploy my 1st linuxmce system.  I have the following:

main server
1 gig ram
1 ide 20gig hd
1 sata external drive 2.5tb
on board ati video controller
2 nic cards

Media computer
1 gig ram
80 gig hd
nvidia GeForce FX5200 card
Gyration mouse
Soundblaster 5.1 digital sound card

my question is would it be better to put the Wintv-150-mce card in the media station or in the server?  and for future expansion where should I put the win-tv-cards?
