Has anyone tried a Hackintosh INSIDE a 21.5" iMac before?

Project updated after a long time.
Full working on Catalina 10.15.3 at this time.

iMac case LCD works.
iSight works with pin out solder on USB.

Tthings left to get work:
Chime boot with arduino
SD card
Bluetooth card
and waiting my case

Have you found out how to re-use the original fans?
