I've looked at the server and it is a 3.3 pro system as sold by HES 4 years ago.

specs are if I'm correct:

Dual 2GHz Powermac G5
1Ghz frontside bus
512MB DDR400 SDRAM (max 8GB)
147 GB ATA (Pro OS and software)
10k RPM 147 SCSI drive
ATI Radeon 9800 Pro 128mb DDR videomemory

I understand I need v4 to use a TH2G? Can I run v4 on this system (maybe by installing more ram?) and does anyone know what the cost of an upgrade are?

with kind regards Joost
