Whilst a vacuum cleaner is designed to catch the dust and not expel it, hopefully the majority of the dust will pass straight through the power supply. However, that's only most not all. So the next question to ask is how dusty is the place where you would be placing the PC? I occasionally need to open up the pcs & servers at work (fit memory, cards, replace disks etc) and the pcs at work have very little dust in them, certainly not enough to worry about. Contrast that with my pcs at home, where they do seem to attact dust - I even have it on my calendar to vacuum them out every 3 months or so (if I leave it longer I can start to hear the cpu fan straining). Even then it tends to be the cpu fan which get clogged up first - although when I'm vacuuming out the case I normally try to vacuum the power supply as best I can without removing it. I have heard it said that pcs shouldn't be placed on the floor because of dust, but I'm not sure how much difference that makes since most pcs at work are straight on the floor and my ones at home (which suffer from dust] aren't.

With the old approach (ie, the power supply at the top of the chassis), the dust needs to travel a longer way from the intake to the power supply. With bottom-mounting, the dust reaches the PSU directly from the intake. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

No it doesn't! In my P180, the PSU is usually the cleanest bit. -- SteveH |
