How much did that run you? I would love to get me one of those things. Still, the reason I like filters so much is because the fine particles take longer to build up, and so your heatsinks stay dustbunny free for longer. It is a pretty hard thing to maintain though, I do agree with you there. Also, how often do you usually clean your computer you think?
It was $200 and included a finish nailer
I don't have to blow out my case very often. I might blow it out every 6 months, but not much dust builds up in 6 months. We don't have pets and there's no carpet where my computer is and then the fact that I keep it up on the desk counts for a whole lot.
Here's an air compressor for $70:http://www.amazon.com/Campbell-Hausfeld ... 460&sr=8-1
and you should consider gettinghttp://www.amazon.com/Campbell-Hausfeld ... y_hi_img_b
You should also check our Home Depot. That's where I got mine and they still have the same kit I got with the nailer in it, but I think it runs $240 regular price. I got mine during Christmas season.
What is great about air compressors is that they are useful for so much more than blowing dust out of you computer! Obviously they fill tires with air, but there's also blowing out your refridgerator's coils (and fan if applicable), blowing off the work bench, pneumatic tools, blowing up whatever balls are around, and even blowing your clothes off if you've managed to get particularly dusty. As useful as it is, it does go for two-to-three month stretches without getting used sometimes.
