Power supply at the bottom of the computer chassis?

So the answer would be Yes, but who knows whether it in fact would. Compressed air is probably better since it is clean. Some people might argue that static electricity really is not a problem, but parts do fail and (since you cannot troubleshoot them) who knows why they fail. Eliminating leads (like static electricity damage) at least might allow you to guess about why something failed. Good luck and have fun.

I do see what you mean. I have a "horizontal" desktop pc at home (as opposed to the normal vertical tower), and the only dust problem I have is around the cpu fan. When I do vacumm it out I always include the power supply, and have not had any noticable issues. If you are considering getting one of these pcs (or if you already have one) then I'd recommend making a note to open it up after two or three months to see how much dust is in there. Then you can make a call as to whether its worth vacuuming out regularaly or not. -- Brian Cryer www.cryer.co.uk/brian

I'd block them from moving by using something nonconductive and tough but not brittle, like a plastic straw. Don't use anything metal because there's exposed high voltage right behind the fan, even when the PSU is turned off by its rear switch. One former American TV manufacturer issued a service bulletin warned technicians about static electricity from vacuum cleaner wind causing damage to chips, but I seriously doubt that's a real problem with a power supply because their chips aren't as delicate.

Just for the record Ive ordered my i7 920 SLBEJ for �230 incl taxes and shipping - should be here tomorrow. What a relief No more hassling over different components. Because I needed a new chip, mobo and RAM there was relatively little difference in cost especially when I considered the time it was taking to decide which way to go Now the decision is made I can focus on mobo and ram. In the end it was between the fast Ford and the Mazeratti - sure they can both do 150, but which one looks and sounds better? I went for the Maz - the six-core Ferraris are for people with deeper pockets. ______________________________________________ 'no fax payday loans' (http://www.unclepaydayloan.com) | 'bad credit loans' (http://www.unclepaydayloan.com/bad-credit-loans.shtml) -- JanetCallersever |
