You may be thinking about 1337 gamerz gang. When you're going cheap, there're lots and lots of ways to save. E.g. you can get a fancy box or you can re-use a two decades cheap box just fine. Or you can live without it entirely... Cheap old power unit will work fine as long as you don't want beefy GPU. It's easy to get hold of older generation CPU/motherboard too which will work just fine for hackintosh. And then get a tiny SSD for booting (or skip this step entirely) and use an old HDD for storage. Keyboard/mouse cost peanuts too if you ain't going fancy. Old smaller display is cheap too. Hackintosh-wise, CPU/motherboard is pretty much the only crucial part.

Hardest part is to get wifi and bluetooth working. But you can skip that entirely to save money and headache. Personally I skipped it on my first hackintosh. Got it working during pandemics for shit and giggles though because a compatible part popped up in local ads. Now even airdrop and continuity works :)
