Yeah, it's on the same server (www.dnuk.com NAS Server):

Dual AMD64 2GHz
4GB Ram
80GB OS Disk
6.9T /storage
SUSE 9.3 64Bit
Quantum SuperLoader 3 LT0-2 Autoloader
LSI Logic/Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)

Just running amtapetype now via "screen", so might just pick one from:
