yeah, i did all the neoprene fitting today,
i will cover everything (inside socket, outside area, between neoprene layers) in grease before the final mount to be sure.
Thanks for the 6mm neoprene tip, i realized after cutting the top piece that it was too thick, now i must shave it, i don't have anything thinner to use.
Tomorrow my Radeon 2900 Pro comes :D
I'm looking forward to seeing a prototype hold-down too ;)
