got this installed now on my dual xeon server SCSI 320 controller. Installed quite quickly but I only installed the CLI as i didn't know what i was doing. So will reinstall the full ubuntu package later, just waiting on some RAM as i was only running on 256MB - bloody ECC ram

On a similar note I am just turning a small Celeron Duo system into a NAS drive - Synology kinda thing but better i had a high end Adaptec U320 SCSI card laying around and loads of drives so will make a RAID 1 array for the OS and add a couple of 2tb sata drives - not sure what controller, maybe southbridge
Till i can upgrade the disk sub-system in the dual xeon, we'll see what happens, but I really need one to be a win 2008 server and one to be linux/ubuntu.

I'll post some pics when finished
