I took in a Dell P690 machine from a client and it's in a constant reboot state. I'm not sure if it's the mobo or the PSU but it's got issues.
If anyone wants essentially a free chassis it's yours if you pay shipping or pick it up.
Machine is out of warranty and it would probably cost $40 to ship.
Will start & run fine but after about 30-35min it just reboots. I think if I had to guess that the power supply is bad and the box restarts.
2x Xeon x5140 CPUs with 8GB of DDR2 RAM and a 160gb raptor drive (that is also throwing a smart error). Has some kind of Quardo FX (something) card.
