Requirements for a new Hackintosh machine

I’m considering getting a custom-built PC from Fenn and was wondering if anyone knows the minimum reqs for a Hackintosh setup, as I'm new to this. Anyone experienced with their systems, shipping & services? Theyre from belgium so idd need to have it shipped which I find a bit risky for such an investement... Bit of a long shot, but tanks for the advice!
