For $2400 at education pricing, I could get:
Acer 350 F1 (yeah I know, I hate Acer as well)
With:
12GB RAM ECC
Dual Quad core Xeons E5606
Dual 500GB Drives
For three years worth I could get the same server but with
Dual Xeon X5650 (6 Core)
96GB ECC RAM
8 Port Raid controller
Dual 600GB 15K SAS Drives
These prices are just crazy!
