Mounting the rad, screws.

So...I just got my BIP II. I marked and cut the hole out perfectly. Drilled some holes for it and the line up just fine. Now what exactly do I use to mount it? I'll have 2x120mm's on there so I'm assuming the screws have to go through it.

I have a BIX and I just used regular, fine thread, sheet metal screws right into the holes that are on the radiator.
The screws will make their own threads when you tighten them in there.
I think on your rad there are 8 holes but I doubt you would need to use all 8.

Ahh, see thats what I was wondering. I didn't know if I needed a nut on the other side of the hole to secure it.

I use #6 Metal Screws 1/2" Long.
