I just needed a pc for Windows 10 to take IT exams for. I did not want to upgrade my main laptop rig to windows 10 it was built in 2009 and was not designed for it. I have not done any heavy use with the pc other than leave it running for long periods of time to make sure it works correctly. I don't like on board graphics cards. I am planning on upgrading the 290 watt power supply and installing a high end graphics card suitable for the specs that the pc has without bottling necking performance. The first couple of days of use the screen would flash black for some reason but after windows updates im not sure how but it did not do that anymore, i tried the top and bottom display port both flickered but it is fine as of now. Hard drive seems solid some off brand name, and so far ram is good i checked the ram info and manufacturer is unknowed for all memory sticks makes me worried but it is functioning. Windows 10 actviated to my windows account i wish i could have activated it without a Windows account attached to it wish i knew how, i do not like Windows 10 and would not upgrade unless I had to take IT exams and they require that for it. I liked the specs, dual display port and the i7 processor was the selling point compared to others if i wanted a cheaper one to upgrade it would cost more to do that. Case had some scratches as expected and back of case by the I/O plate was a little bent i just gently pressed it straight again. I guess value for the money.
