m8?! if that is the case you have damn good mounting of you'r mobo.. isn'nt ist 4-40UNC (?) or if not i think it's 3mm
Ah HA!!! Drive mounting: 6-36ns Case cover: 6-32nc Motherboard standoff: 6-32nc Motherboard standoff screw: 1/8-44nf as per THIS SITE.
woops.. it was the connectors that have this screw fastening that uses 4-40... i thought they was the same... *pulls out a connector and a standoff* nope.. doesn't fit..
Thanks Dad, I've added it to my modding bookmarks. I didn't want to drill a nice new shiny piece of aluminum with too big a hole
