MP 1,1-5,1 5,1 PCI lane fan cage disassembly

[ChipSpencer]

I’m rebuilding my 2010 Mac Pro 5,1 and replacing the stock fans with Noctua 3-pin ultra quiet models. What I’m having difficulty with is disassembling the pci fan cage.

I’ve removed the two screws but I am unable to determine how it’s still being retained.

I looked at the clip holding the pin for the button and it looks like it’s part of the housing and not a separate piece.

Any suggestions on how to disassemble this cage? TIA.

I've finally managed to do it Didn't find the 3mm hex screws at first, but then it was still stuck after unscrewing them... I slid a Jimmy between the button and the cage (where the PCIe slot numbers are) and it snapped loose fairly easily.

There's a position at the end of the slot where the outer cage can be carefully forced to slide over the inner casing.

I soldered the wires and used Maxwel High Temp wire harness tape
