Pre-install query

Hi,
My network compries:
Server: running Ubuntu 10.04 LTS Server (no GUI), up 24/7
PC1: running Ubuntu 11.04 Desktop (with GUI), up on demand
PC2-4: running various Windows versions from XP to 7, up on demand (not really in the equation but for completeness)
TV: SONY (2010 model)
My understanding, from research I have done on the net, is that my installation would be as follows:
SERVIIO installed on Server and PC1. Server will run serviio.sh, PC1 will run serviio-console.sh (with linking to Server). Music, pictures and video libraries stored on external USB hard disk mounted on Server/mnt/OurMedia updated regularly with new additions.
My question is:
Which machine will maintain the SERVIIO database? Will it be 'Server', on 24/7, or 'PC1' which is only on when required.
Kind regards
