mine is 2 small to do anything in i used my mates to spray the first lot of plastics up but hes gone on tour now so cant use it.
of course u can do it

ive never touched a pc apart from a few weeks ago most of it seems to be common sense and artistic license when it comes to modding a case or fitting wcooling by the looks of it

i may be wrong and end up with a massive leak and 3k down the drain haha. but so far just feels like building a massive lego set
