It works! - for audio anyway
FYI
Hardware Spec;
Pentium 4 630 3 Ghz on intel D945GTP board -
http://www.cpubenchmark.net/cpu_lookup.p...+4+3.00GHz
2.5 GB ram (running at 266 Mhz) -
Geforce 6800 GS 256Mb
3.5 TB on two drives connected via USB caddy (to be move internally)
M-Audio Delta 1010lt sound card - 4 stereo phono outputs
Cut 2 phono leads in half and crudely wired through a simple blocks (Upgrade
http://www.ebyelectro.com/terminal-block...ewless.asp) to speaker cables that run through my house then into two speakers in each room
Software
Windows XP 32 - (to be changed to server 2003 64 if possible)
XBMC (4 separate folders on external drive - Run side by running in portable mode as different windows users outputting to different audio devices- wasn't able to achieve in windows 7/8)
Virtual Audio Cable - to allow switching of audio into more than one room (can use xbmc mutliroom audio plugin for two audio output)
MySQL - to manage single database
Xbmc remote on android (assign different port for each instance) - minor issues controlling volume and next track etc.
Performance;
Each instance seems to use about 20% CPU and 30-40mb of Ram with all playing music, much lower when idle
The sound levels are not fantastic but OK for my bathroom and bedroom running but I'm running the sound back into my stereo in living room for amplication
Given the low spec of the CPU and GPU I'd be surprised if this cannot be replicated on a small €200-300 pc
As for video I might get 4 old lcds and test it as the pc has original on board VGA and DVI + the Geforce ones
