LOL MadHacker, too bad about the neighbours,
mine never said a word except giving me an eye when told what I'm making (u know, they politely ask what's goin' on, and when told that it's a watercooling for computer, you gain that 'look, nod, nod, eye' :E

maybe you should try to do it in afternoon, here nobody complains if you do your stuff after 5 pm till say 8 pm or so, it's considered mostly OK...
