And nobody mentions the cost of maintenance! What brought me to hackintosh in the first place was my dead GC in a 2008 iMac that I couldn't change myself (here in Europe) and had to go to a certified Apple repair shop where I spent 10 times what I would have spent for a basic PC GC...
Yes, the cost is different now, that's why I wrote "if you don't aim for the state-of-the-art".
In the OP case, I trust @trs96
for what he wrote about a high-end production machine.
I agree with @phunguss
and I add that you'll be able to use also used PC parts (or convert existing HP and DELL machines) for a long time, if you don't care for the latest MacOS version and you accept the (tiny) risk of decreased security.
