I have a cheap azza that came with my old PC. I like the feel of it while typing. So I don't mind loud at all. Wired
Mouse preference, right now I'm using a logitech 9.99 mouse, so definitely wired, but other than that, I'm up for suggestions.
I have no preference on build, I listed what I need to do on the PC, I prefer smaller, but I wouldn't care if it was midsize or big, its just in the corner
