hi after about 2 months i finally decided to clean my case for dust. then i found ALOT of spider webs.

Im just asking how it got inside my case and can they pose a threat to the hardware? i have built this pc but i never encountered an issue where a spider nests inside. 

Yes they can pose an issue, if they get sucked into your heatsink fan they can quickly clod the fins and overheat your PC .

I would suggest you close up ant openings to the inside of your case, If you have open fans I would suggest a grill for them that has a screen to cover them, and make sure the rest of it is sealed up.

 i found ALOT of spider webs.

 

This is why its always a good idea to keep a few Marimbondos around the ole' system build. The Mariam-badboy, or "PC Keeper," as we call it here in Maine, are long-legged, solitary wasps that use spiders as a host for feeding their young. They paralyze the spider with a venomous zap. Eggs are laid on the abdomen of the spider, and as they grow, will begin to eat the Spider. The Spider will  have an excruciating last few weeks, and the Mariambadboy will be on its way to the next enthusiaist.

See, so not only do you get great protection, a.k.a. a larvae firewall, you also have the added pleasure of knowing the Spider is tortured to death for even thinking about going near your rig man! Who said revenge and spite couldn't be fun.

Peace, Penewah!
