just about any mechanical keyboard will be alright - i take mine to bits all the time, i mean literally, into all the pieces
Without hijacking this thread any links to sites that explains how to strip a mech board for painting?
Cherry G80-3000 is nice and easy. The shell clips together with huge hard to break tabs, not even the PCB has screws just friction fit. Unless you want some unique finish, using vinyl dyes is more recommended than regular paint for durability.
A mechanical keyboard was my initial thought too & I would go for a 'cheaper' mechanical keyboard too (like the g80-3000) so there's less to lose if you stuff it up... How to dismantle the board would vary depending on the board itself. Most are fairly simple with a couple of screws (or maybe none) and plastic tabs that hold the top shell to the bottom - I find sliding a credit card between them helps to pop open the casing...
This question has got me in the mind to paint a mech keyboard also. Damn you TheGreatSatan. No sure I wany to pull apart the ones I have though. need to be on the look out for a cheapie.
It's honestly EASY to open up mech boards. I use credit cards also to pop the top shell from the bottom. I'm pretty heavy handed, I've not broken anything yet. My keycool I think i've had the top and bottom shell apart about 20 times at least, and the top still fits back on the bottom as well as it did when I got it.
I might just have a go at my CM Rapid Fire then as that was the cheaper of my two boards. Will need to think about it and decide on a colour as I have red and white keys on it just now.
