The workstation came with the listed specifications, including an Xeon E5 2620 processor, a Seagate HDD with an HD 6670, no RAM, and an 8GB ECC SSD. After some time, the machine would repeatedly power on and off. The seller replaced the motherboard, swapped in a new CPU (E5 2630L), and provided a replacement ECC RAM kit.
