I currently have a Dual Opteron with 2 GB ECC Registered RAM and dual 73 GB SCSI drives in RAID or dual 80 GB SATA drives in RAID which we could easily bump up to 4 GB. I also have a couple 2.4 celerons currently available. We've just run out of our P4 2.8- 3.0's although it wouldn't take long for us to get those in stock. We also have a 2.8 Celeron available..
