MacPro 3.1, 4.1-5.1 ATX Bracket

by StefBond

MacPro 3.1, 4.1-5.1 ATX Bracket (possibly will work on 1.1-2.1 needs confirmation), designed to work with ATX, uATX and ITX motherboards. Has a standard height of 15mm, the same as the original MacPro motherboard. You will need to modify your case, as it will need to be fully cleaned from original brackets and boards. Check other parts in my profile for a complete ATX conversion. You will need a "MAX" 3d printer since these models require up to 300x300mm build plate. Mounting holes are meant for M3 brass inserts that are commonly found on Amazon or Aliexpress. The ATX bracket is mounted to the chassis by using M3x6mm Socket Head Screws, and additionally, it can use some glue, but optional, depends on how heavy your board is. https://www.youtube.com/watch?v=60bBMA3KMJ0&t=147s
