It's my job to clean computers, and this doesn't shock me!
This is what I actually love about my job. People bring me their computers in, saying they're crashing and freezing, beeping, etc, and all I have to do is spend 1 - 2 hours dismantling everything (completely), cleaning it, renewing thermal grease, (and sometimes the fans if they're burnt out because of the dust) put everything back together, and that's £22 - £44 (£22ph) worth of food on my table, and the customer's machine is spotless. I keep the pile of dust, and cam pics for them, to shock them!
I do this about 7 - 8 times a day, and just the computer cleaning side of my company repair skills earns me a lot on really good weeks, before the actual repairs come in! I've seen spiders, dead hedgehogs, ants, bluebottles, centipedes, woodlice, you name it. It is well worth it, I love my job as a self employed repairer, and despite not liking spiders, wouldn't swap it for the world. I'm a big softie too, and like animals, so seeing dead creatures like hedgehogs (how they got there is another story) inside PC's saddens me, but that's life.
Luckily it's only ever dust, and the occasional insect inside consoles and laptops I do. FAT PS3's get the biggest insects in, having a lot more vents than 360's. Ants seem to think PS3's are fairgrounds, and like having rides on the blades of fans, so much it kills the little blighters, good riddance! It's quite hilarious imagining their little faces as they whizz round and round, their bug eyes popping out!!
