First of all sorry if this is in the wrong section but it is mostly about my case. This week (probably friday) I will be receiving some stuff from newegg I ordered and one of those things happens to be my new PSU (Corsair 850tx). Since I'm swapping out the PSU I thought I might take the time to get all the dust that has been building up over the last year off my parts. Is there any special way of doing this? Do I just blow it off, use a cloth? Do I have to buy a cleaner kit or something. I'd really not like to have to spend any money, but if I have to at least I would like to buy it locally. Any suggestions?
