I used Arctic Silver adhesive though, worked great, took about 1/2 hour to dry until it was stuck on for good. I made my alum slab 42mmx29mmx3.175mm(1/8").
However, I should made it 27mm wide instead of 29mm, as I had to perfectly align it with the board, even then, it was slightly crooked, and was tight fitting when I adhered it to the case.
Also, my board didn't seem to be flat , because the two ends were off the slab by a hair, nothing the adhesive couldn't take care of.
One more thing, the button was pushing in the top 'button cover' pretty good, although it didn't activate the button though. So I took the cover off again and took a exacto knife and scraped .5mm off of it, as there was a nipple on it. Now the button cover sits down the way it was before.
AGAIN, you MUST use adhesive for this mod, otherwise there is no point in doing it. Paste simply is simply not sticky, it's a grease, and the board will just flop around in the case.

not exactly true. that's why i was asking how much pressure there is. I test mac upgrade processors, and we basically have the heatsink, thermal paste, shim, thermal paste, cpu die. the pcb is screwed to the heatsink at the 4 corners, but there's more than enough pressure on the die to keep everything in place, even in hard impacts..
