I'm very new to this computer stuff and I'm looking for a budget pc under $200 for just csgo gaming, i found an hp 8000 desktop pc local to me for $80 and i was wondering if it could fit a: Gigabyte Nvidia gtx 750 ti 2gb gpu into it, i was also wondering if an intel core i5 2400 sr00q would fit, and lastly an evga 400w power supply. Thanks a lot and if you have any tips on what to get if these don't fit, let me know! I'm new to this stuff and need help!
