Bargin HP Proliant DL380 G4

I picked up a used HP Proliant DL380 G4 on Ebay to add to the "farm". This machine comes with two dual-core Xeon 3.4G CPU's and 6Gigs of RAM. It also has six SCSI drives that I have set-up as 3 separate RAID1 volumes.
I have configured it to run Ubuntu 64-bit 12.04 and at the moment it is attached only to PrimeGrid with the hopes of finding another Titanic Prime.
The only hassle is that it is a little on the loud side ...
