Summary

I hate original PSU location it makes bed leveling annoying. I didnt want to post this originally but there you go, it is far from perfect, you need to cut a lot of original metal case and throw away original 30mm fan and use 50x10 instead. you have to figureout how to put it together. There is place for buck converter if you want to use it.

You will have to crimp new longer cables for main switch.

Things you need
3pcs M3 inserts
2pcs M4 T nuts
some M3-M4 bolts
2pcs M4 nut
4pcs M4 countersunk bolt for mounting psu to main
some glue for grill
some self tapping screws
