there are a 2 2600s in there, not the latest but pretty new, we got a few 7600 and 2 XR 12000. the rest i think are 3100 not to sure off the top of my head...
but these arent all the racks we got, i mean we have more that those cause we got a lot more hosts to look after and we had just pulled these ones apart at the time... so ye i just showed you those 2 cause i thought some people on here might be interested.
