Ok here is a couple pics of the plate on the M that I bought. I want to bolt mod it mostly for the experience on doing it plus the top plastic plate needs more cleaning than just a simple wipe down. It looks like a combination of a gamer that lived at his PC (more crud around the wasd cluster) and a short hair cat has been sleeping on it for 10 years. All of the keys actuated clean except for the 7 on the number pad.

The board chow.

Would you guys consider this a good candidate for a bolt mod? Also are the 2-56 or the 2mm x .4 screws preferred? If there is really no preference I was planning on going with the 2-56 just because I will be needing some of those for M-64 including tap and other stuffs.
I have found Ripsters bolt mod guide and seems detailed enough that I should be able to pull it off.
Any other tips I should be aware of? I already have this thing apart as far as I can go before destructive means would be necessary.
