I have been stetting up pc computers for many years because of the kind of business I was in and this one has been the hardest one I've ever had to set up. I still can't get the green speaker port to work in the back? Still can't get all the USB ports to work on the front to be recognize ?  I called the help number with HiTech  over 2 weeks ago and am still waiting for a return call. I'm using the PC but not happy with it. I guess you get what you pay for!!!
