hey antique, you gotta take care of that dust, not good at all.
remove your heatsink, psu and air dust that thing out. You'll be amazed by the amount of dust that will come out.
Another way to stay neat is using sata cables for your hdds(you will need a sata hdd)
using zip ties will help, their are many other methods too but this would be a good start.
