You need to buy hardware specifically for hackintoshing. Don't just buy whatever's in fashion and try to make Mac OS fit.
If you do that it's mostly hassle free. Never had freezes, had stuff like sound not working when coming back from sleep (which i solved by switching to usb audio).
Of course, then something will come along and fuck you up, like Apple dropping nvidia drivers completely. Which is solved by getting an AMD video card. Admit it, it was time you upgraded the video card anyway :)
HP 6300 SFF: $35
NVidia GT 710: $30
16GB of DDR3: $60
Cheap 256GB SSD: $30
More than fast enough for me. Everything works: iMessage, iCloud, etc. No crashes, no freezes, no audio issues. It started on High Sierra and is on Mojave now. Installation straightforward, though it requires concentration as you read the instructions - and no cheating.
It's a low profile card and I don't remember it needing any power being plugged in. To be fair, I think this card is overpriced for whatever performance you would get out of it. That is especially considering I only use it for 2d acceleration. But I needed the card because I could not get displayport from the motherboard working - I suspect it is the particular CPU. Regardless, my entire outlay for this machine was the price of the graphics card.
It is fairly quiet, but I've never heard it really ramp up.
I do vaugely remember the card NOT coming with the shorter edge connect (metal L bracket thingy). Need to look back there and see what I have going on.
