A ShopShield filter will screen the dust out before the air goes in the vents. There are pics at http://www.computerdust.com/

A pillowcase might also do the trick. :P Just make sure it's really thin and non-flammable.

Nice setup. Whered you find the pedals with a clutch? ive never seen one like that

I've never had a problem with static. I've even accedentally dropped parts when building or rebuilding a computer and they still worked. Also, I like your setup. Is that computer custom and what's that below the fan control?

Hmm Id be worried about static from the vacuum on parts *eek*. I usually clean my computer of dust every 3 months (or every season I should say) with a Air Compressor. If your allergic to dust, its best to do it outside. Besides allowing your computer to run cooler, It can also make it a bit quieter..Some fans can get quite noisy when full of dust.

What's this about a vacuum on parts? > Sorry Sir, We've had a slight problem with your computer health check. < What do you mean? > Well, we used a vacuum and now your chips have been fried. < Really? Can I eat them? Lol. Out of all the computers I've worked on, none of them are as bad as the one i'm using now... The fan sounds like a pneumatic drill when the machine is first starting up.

Vacuuming is actually the recommended way to clean collected dust in a computer and other electronic devices. If you force (or blow) air to remove dust, some can become lodged in small moving parts such as fans, CD or DVD drives and hard disks. This can cause problems as minor as a fan not running at it's full speed or as bad as shorting out drives or frying a processor due to overheating.

Air compressors can be just as dangerous to computer parts, because unless you have VERY good air/oil separator (also called filters some places) the air from the compressor carries small amounts of oil and blasts it against your components. The oil is bad for several reasons, mainly heat transfer and that it can be partially conductive.

Some (usually smaller ones) air compressors are oil-less. The thing is, rapidly moving dust particles create a static charge, air compressor is dangerous like a vacuum is. The same is true for canned air, it generates static. There are only two truely safe ways to clean, one is agitation or force of sprayed liquid (how the manufacturer cleans them to get flux off after soldering), the other is a paint brush with anti-static treated bristles to get the dust loose then a very mild compressed air like a fan, not powerful and fast like the previously mentioned methods of compressed air or a vacuum. It is certainly true that you can clean it the "wrong" way and not cause damage, just as someone can build a computer without a ESD strap and often do no damage, but it is possible to do damage and since we are talking about that, I mentioned it.

Really? I did not know that, thanks. Ive been cleaning all my computers for years with a Air Compressor, either I have a good filter, or ive been dodging a bullet.

As long as you have a good filter, you should be fine, it's just something to think about. I know a lot of computer repair shops do use compressors, so it's obviously no going to straight out kill your computer. Just a word of caution. I know I wouldn't use my shop compressor (big, industrial, very oily) without a serious filter.

Funny thing is here in AZ my pc looks that bad in a month! Back in Chicago it would take at least a year to be that bad! People with dogs and cats that walk around all over the house it gets worse though I've seen!

JESUS CHRST! HOW COULD IT GET THIS DUSTY!!!!!! :O

I recommend and use "canned air". It's actually difluoroethane.
I average 2-3 computers a month cleaned this way, and never had ANY complaints. It is best to do this outdoors, or in a dust collection hood, and the dust will fly all over the place.

using a vacuum give a small risk of sucking jumpers off of the board. SMALL risk, but it's there. mainly, if the sucking end makes a seal against the board while the jumper is in the "area of effect" of the vacuum.

An air compressor MIGHT be ok, in many circumstances, but it holds the risk, not of oil contamination, but WATER contamination. Without a proper air/oil filter, the atmospheric moisture gets compressed along with the air, and ends up condensing on the pc boards. Water + electronics= bad.

The canned air has the advantage of being an electrically inert fluid/gas. It too has a risk though. the high speed/flow of the gas CAN over-spin any fans you spray it with. Especially really small laptop cooling fans. To avoid that problem, I "immobolize" the fans with a plastic toothpick before dusting them.

Nice pictures! I clean my PC out every once and a while. Since I only have one fan, there is a pressure difference and the dust is sucked in. Makes for a pretty dirty heatsink.

If your powersupply is at all new, you should not open it, and that will void it's warranty. Otherwise, this is a great guide.

I just cleaned mine out, I installed thin cloth filters over the big inlet holes on the rebuild.
I'd like to remind people of this piece of wisdom: "If it ain't broke, don't fix it". There's a risk of damaging your machine by taking it apart, unless it is overheating and needs a clean, a bit of dust is more of a cosmetic problem. Although you seem to have accumulated a lot of "stuff" in that - got pets?
