I picked mine up at FedEx at noon and it's been sitting on a kitchen counter "on" since. I think I remember concerns about heat. I just got out my meter that has a thermocouple probe for temp measurement and checked all over the top cover. The warmest area was 4" to 6" in from the back on the right side of the unit and about the same 4" to 6" in from the right. Max reading was 39 degrees C = 102.2 degrees F. No problem - just give an inch or so clearance above the top, and with open back and front, it should be good to go.
Tomorrow I'll remove my old 950 from my equipment rack and replace it with this 975.
