nah none mate. first off all the piping doesn't go all the way into the tower, its about 2 inches short , plus its on around about a 20 degree incline so any condensation that forms inside pipe will form and run down outside the tower into a bottle, and as for inside the tower itself , there hasn't been any condensation scene or evidence of it forming inside. i don't believe there will be much of a chance of condensation forming in the tower itself as the temperatures inside the tower and outside aren't greatly different , yes the components get hot but the general inside temperature is relatively similar to the outside , as the air con still keeps the room cool as well as the tower .
I maybe a raging homo , but i got this lol.
