Step 12: Cable clean-up and you're done!
You have now succesfully assembled your computer, but a myriad of cables are still visible inside the case. For a see-through case this obviously isn't nice, but even if it is out of sight you should do something about this. Less cables in the way means better cooling, which means less risk of your computer overheating.
Tidying up the inside of your computer case is a question of bundling cables together in different places with cable ties. Some cases have loops here and there where you can attach cables to.
Once you have cleaned up the cables, you can put back the side panel and close your case. Congratulations, you have just built a computer!
