Building a PC

[biftek]

case ventilation is something you should take some time to fix up , keep the dust build up down , tie your cables together , can buy some garden hosing stuff slice the hose down the middle shove your cables in the hose that use some of those zip ties to keep the hose and cables together

ide cables are another thing , can get some rounded cables or can you make your own by carfully slicing the ide up , then again use some zip ties to secure the cable

intake and exhaust fans also , try to keep a pc a few inches away from walls so that the exhaust can work , and don't have your case enclosed in desk space
