1st. Clean your fucking desk. You only NEED two speakers. And your headset gets rid of speakers at all.
2nd. Get rid of the makeshift. Sell it on eBay?
3rd. Laptop could be used as your portable gaming? (like it's actual intention lol)
4th. Draw airflow in from the right and out the back. raise the motherboard to atleast 80mm above the bottom and throw in an 80mm fan to guide.
