For my own part, I don't think the keyboard needs to be able to withstand a nuclear blast. I don't transport my keyboards, and they tend to stay on my desk quite well. No cats hopping around to mess with them. For clarity's sake, I'm not being facetious, I'm just of the opinion that the two boards discussed so far are probably more than adequately made to suit my purposes. YMMV.
The more we discuss it and the more I think about it, the more I'm thinking of actually doing a switch transplant on my at101w. I'm tempted, whether or not I do that, to buy one of these other boards and have that as a comparison. I'll have to work out the particulars. Part of what is encouraging me to go for the transplant is that I have a chicony keyboard with mx blues in it that I enjoy using, but it's been having reliability issues. I replaced the capacitors in it and in some ways that seems to fixed the problems, but not entirely - I still run into trouble with it. It seems to have difficulty operating while playing a game I've been really into lately, Heroes of the Storm. That is possibly just coincidence, but I recall it not working a few times while I was running that game. So, I was considering harvesting all or at least some of the switches and trying my hand at wiring a keyboard. I realize that's a bit of a step up in some respects from replacing the switches in the Dell keyboard, but it does have the advantage of I already have the switches for the project, and it doesn't much matter to me if it doesn't work out. The experience will be helpful. Either way, I'll having something to build on in terms of putting matias switches in the Dell.
On top of that, I figure if I'm going to take the Dell apart, I might as well try some light customization (paint, namely, but perhaps other things). I've started looking into the particulars of all of this; there is a hodgepodge of information here and there. There doesn't seem to be a definitive guide, but that's okay. Other people have managed, and I will too.
