Sphynx, I don't think there is anything wrong with cleaning your machines once a year! In fact a lot of my IT buddies swear by that. I think you're part of a bigger minority than you think at least from the people I know. Half of the IT guys I work with don't even like computers! Personally, I just like to tinker and mess with things. Not at work, just my own stuff at my house otherwise I wouldn't have a house. I haven't lost anything yet and I'm hoping the PSU isn't one of them. Did it take out anything else with it? I've only heard horror stories about people (here comes the stupidity part Shandia) building their first computer not realizing they got a PSU too small for the system to run on. (Definitely not me ) I honestly think your plan is a good one and maybe I should tone down and have a few beers myself
