+So we gained 340 MHz / core if we ignore Turbo mode, but we also

+Nice controller.
+

+
+Back to sata speed disks

+I'd rather take the old one then, add 2x300GB in raid1 and 2x300 in
+raid0, and add 32GB ram to that one...
+
+
+Or as a different proposal...
+
+What if we make ecosse our new rabbit ?
+
+It has dual Xeon 5000 series Quad core running at 2.66 / core
+(so 8 real cores available)
+
+It currently has 8GB of RAM
+
+We would need to buy:
+- a new disk controller (as the current integrated ESB2 one sucks)
+- 2 >= 300GB SATA disks for system, frozen repo and readybuilt isos
+- 1 ~250GB SATA SSD for iso builds
+- maybe some more RAM
+
+The cash saved could be used instead for the replacement >= jonund-class
+buildhost.
+
+Would that work ?
