[Josephdalepi]

clean it

get new fans

get new hdd, as itll work better, and it doesnt sound like he needs an ssd

new cpu cooler may be quieter, but it doesnt sound like he needs it

Well if it was never opened it first probably needs a good cleaning, after that check how it's doing, if it's still really loud then looking for some new case fans and coolers would be a good next step.

Id just move it to another room and get really long cables if you dont wanna spend a fortune on noise dampening kits/new fans

And this spells the extent of the problem. Fans have to be cleaned out periodically to clear them of dust -- both off the blades and out of the motor. Get a can of compressed air and keep the vacuum handy. Run the vacuum near where you're spraying the compressed air to collect as much dust as possible. A synthetic painbrush will come in handy to knock loose any stubborn buildup.

Beyond that, you'll likely need to replace any fans currently in the system. Since it's 6 years old, it likely uses 80mm fans, which there are some good quiet options out there. Enermax makes a good option, as does Noiseblocker, though it's a bit more expensive. It'd also be a good idea to buy new thermal paste since you're likely to need a refresh on it. You can find tutorials online about how to clean off the old and apply new.

Do all of that and it should have things running pretty well.

Have you identified the loud components?
