Very disappointed with this purchase. Upon receipt, the tower was full of dust and the fans were completely caked with grime, proof that even basic cleaning hadn't been done. Even worse: The thermal pad for the NVMe was missing. Right from the very first power-on, the PC asked me for a session/administrator password, completely preventing me from using it. The checks and factory reset promised during the refurbishment clearly weren't carried out. A refurbished product should be clean, checked, and ready to use. I do not recommend this seller.
