So far, I've purchased two of these mini-PC's. Both PC's look like new. No dents, scratches or other physical imperfections that I can see. The first one I purchased came with a built in wireless adapter and antenna but the second one came with a separate USB wireless adapter. This doesn't mean much to me as they are both connected to the network via Ethernet cables. FWIW, one PC has an "AData" brand drive and the other has a "King Win" brand. Both PC's had Windows 10 Pro installed and I didn't need to activate the license as it had apparently already been done. Great value for the $$.
