for the price I had no problems, it was easy to set up , it took a minute to find the windows key because I didn't read the complete quick start guide. the key is  half covered by security tape and you have to scrape it off to read it to activate. No problem activated fine. The pc is fast I have it hooked up to Ethernet and average internet  speed is about 100 mgs. It came with a wireless adapter to plug into one of the many  USB ports but I dont use it.  I use two monitors one is plugged in to the vga and the other to display out. I had to buy the display cable separately.  all in all a good deal.
