I was almost discouraged from buying this from the few negative remarks but.... I found it to be complete with no missing components. The wifi and antenna were present and in working order. The power supply and jack were there and appropriate for this unit. It fired up first time and updated for bios and win10 right away. I've paired it with a 24 inch Acer display and it works perfectly for my needs. I suspect that it wouldn't run resource hungry games but the graphic card is more than adequate for my needs. It loads up quickly and programs run with no glitches. It's too old for Windows 11, but for as long as they support Windows 10, I'm happy with it. Recommended.
