Apparently my case is meant to place the power supply at the bottom. after a year I kept getting blue screens of death. So i looked into my PC and I was like ''hmmm I don't see anything wrong here'' I finally looked at the bottom and i was like ''Oh lawd''
you know that you need a hell'a strong of a vacuum cleaner to suck things out of little places. blowing into computers is way better for removing dirt. you know how much sucking power would you need to remove the kind of dirt that blowing does?!
