Product works and functioned as expected. Quality is lacking a bit. The M.2 SSD was not installed properly. There was not a screw holding down the chip. One of the USB ports have stopped working on the front panel of the product. The usb wireless Internet card is junk. It drops connection often.  I upgraded  the Ram to 16 Gb. Installed a m2 wireless card with antenna. It is a great little home PC with those adjustments. Great value for the money and fast for rebuild. Both keyboard and mouse worked upon arrival. Heat levels I have not tested. There is. Fan over top of the m2 SSD. PC is not suitable for gaming.
