Helping a friend move his stuff over to a new case. ( Icue 4000x rgb) The HP EliteDesk 800G1 Motherboard doesnt use a standard back plate mounting holes. I tried to just use the tabs with the screw holes but the cpu coolers screws are too big. Any Ideas other than getting a new motherboard? New Cooler and modify a plastic backplate and use its threads? Nylon/Plastic nuts ?
