so i know not many people run a horizontal PC build. but its something im thinking of doing seriously. this is due to my gaming rooms configuration. i dont have the height to support a tall tower. so heres my thoughts.

Lian Li 011 Dynamic. remove the feet. install some feet on the metal panel side. lay case on its side.

install 3 exhaust fans at what used to be the right(top). and 3 intake fans at the left(bottom)(by the graphics card to blow onto it) as well as a 360mm radiator with 3 fans as intake on the bottom(side) this would draw in air for the radiator to cool the cpu. and the height difference would be minor between the headblock and the radiator. and if im using a MSI MAG CORELIQUID 360R which has a pump in the radiator then the pump would always be submerged fully.

my only concern is that this config still might result in some air in the headblock. since the highest point would either be the tubes, or the headblock.
