  • Dual 1.4-S GHz P3’s
  • 4 GB RAM
  • LSI Logic MegaRAID SATA 150-6
  • Two WD Raptor 36 GB, RAID 1
  • Four WD Cavaiar 500 GB, RAID 5
  • Six hot-swap bays
  • Intel PRO/1000XT Server NIC
  • Seagate Scorpion 6 Tape DDS-4 autoloader (not installed at the time the picture below was taken)
  • Basic DVD-ROM drive
  • Windows Server 2003 EE
