Prior to apple silicon, hackintoshs were general accepted by a largers swath of people, now as you mentioned its more closely aligned with hackers (and hobbyists)
What were the main goals of people going the hackintosh route? Other than techie tinkering.
I would think possibilities might include...
1.) More powerful CPU options at lower cost.
2.) More RAM module slots without having to pay the cost of a Mac Pro.
3.) A tower unit with multiple drive bays without paying for a Mac Pro.
4.) I don't know whether more powerful external GPUs functioned with them.
5.) Getting their system cheaper.
6.) I suppose if you had a tower with multiple internal drives, you could install MacOS on one and Windows on another, so you'd have in essence 2 computers in one box without needing emulation or the old Bootcamp route.
These days, a person can get a powerful Mac CPU with a Mac Mini (M4 or M4 Pro). With system-on-a-chip, user upgradable RAM isn't workable. I doubt external GPUs are, either. That said, there are options for expansion.
For extensive ports, an external dock.
For multiple drives, either stand-alone external SSD drives (USB-C 10-Gbps or Thunderbolt 3, USB-4 or Thunderbolt 5/USB-4 V2), or what amounts to a NAS-like DAS (direct attached storage) 'box' with multiple discs (possibly in a RAID array) like an OWC
Thunderbay 4 or
Terramaster D8 Hybrid HDD/NVME enclosure (10-Gbps USB-C). Or, for that matter,
a NAS.
