I had this PC in operation for a short while before the provided power supply failed. Luckily I have a battery backup for this PC and was able to continue to operate.I contacted seller via Amazon and had a quick reply. The seller was able to help me acquire a new power supply and stands firm behind their product.This pc is being used for data acquisition and remote visibility and so far has stood up to summer heat in a nema enclosure. We'll see how well it does when the zero degree weather sets in.I would definitely purchase again.
