This is a nice and solid built industrial PC with a hefty heat sink and no fan. I opted for an i7 with SSD version for future proofing. It arrived with rattling noises so I had to open it up to find out what it was. It was just a loose screw that probably would have fry the mobo had I turned it on with out checking. No big deal coz it could have come loose during the shipping.Like many other reviewers here, I intended to use this as a remote PC for my astronomy observatory and telescope control; some 120 miles away. It was a surprise to find out that there is no option in the BIOS to start upon the power is restored. So, I'm not sure how this could work remotely without leaving it on 24/7 with a UPS. For an industrial PC, the lack of this option seems odd. Perhaps this would be reconciled in a future bios update. It's powered by a 12V power supply so I can tap this into the existing 12V bus that powers all other equipments.Overall, it's a solid product but do check for any ratling noises before turning it for for the first time.
