[Question] Bought a PC looking to dual boot it but i'm not sure my specs are on par for a Hackintosh?

I just purchased a LENOVO THINKCENTRE M82 MT with windows 8 Pro for $70

Desktop PC/ Mini Tower PC Processor:INTEL CORE i3 3220 3.30GHz Video Card: Not sure? intel graphics RAM: 4GB (will be adding 4 more = 8GB Ram total is that enough?) SATA: 250GB (Also have a SSD coming in) System: 64-bit, x64-based processor WIN 8 PRO

Im pretty sure i'm going to need a graphics card but i don't really have any knowledge on the pc i bought nor how graphics cards work with a non ATX like board.

Any help would be appreciated.

Im mainly looking to keep windows 8 pro while dual booting Sierra via clover if applicable. also apologies on the format i'm on mobile.
