This is my 3rd hardware swap build in 6 years old Corsair Carbide 300r case. I have limited air flow options so i have decided to put 360 radiator in front of the case with 6 fans ML120 PWM fans in push/pull configuration, 2 top and 1 back exhaust fans (9 total) to cool my Intel Core i9-9900K CPU. This case came from times when RGB was not a thing, no transparent side panel and lot of people still used DVD-ROM so i had to DIY modify the case, remove DVD and drive bays and drill more holes to the front panel. I wanted full black stealth look, buth they messed up my PSU order and sent me white RM850x PSU with white cables so i have decided to go full black & white color theme.
