I got my compaq 11800 today. For the money it is a decent board, but overall I feel like the cherry point of sale boards are much better quality and around the same price. The compaq are used as server kbs, so they seem to be much cleaner/less used than POS boards I have used so far. I have 2 and the trackball is non functional on both of them and have heard it is not any good anyway. The size of the keyboard is pretty good (much smaller than cherry POS boards).
The keys feel very soft, but I tend to bottom out a lot which makes a fair amount of noise. I used the brown springs to make ergo clears which, so far, I like the feel of best and are easier to not bottom out for me because they are much more tactile. If you are planning on gaming, the compaq is 2 key roll over (2KRO) which means you can only press 2 keys at a time and it still work (which is bad for gaming since depending on the game you will be pressing up to 5 keys at the exact same time), you want a 6kro or nkro board for gaming).
I have not tried mx blues yet but have heard they are pretty noisey. Cherry ML switches are the quietest I have tried because they actuate very quickly in the keypress and feel linear so you can type with as little noise as possible (but these switches have no tactile feel which I dont like). I am a pretty new geekhacker but I hope I helped. Welcome to GH.
