The STH10 is ready for any amount of radiators you can throw at it. I was able to fit three 120×4 radiators, a 120×1 radiator, and a 120×3 radiator inside my sample. I still had room for another 120×2 in the bottom compartment as well. With the right hardware you may be able to fit more. The vents for the radiators that CaseLabs has come up with keep the case classy while maintaining good airflow.
Overall the case is huge, aesthetically beautiful, and most importantly functional. It’s everything any enthusiast would want in a case. Not many cases can also be used as an efficient test bench but the STH10 can, with the easily removable motherboard tray, spacious room in the main chamber, and expandability.
