Hi!
I have a A1200 towerized into Elbox E/Box Tower.I've throw away the side covers and replaced them with transparent plastic plates,on the right side I've mounted a 120mm LED Cooler Fan by Revoltec wich blows huge amount of fresh air inside.I've also changed all cables inside to "roundies"-they are increasing air-flow and looks really good when I turn on all my cathodes and LED's inside my Amy.Since these modifications I've never spotted any freeze. Case-Modding could be not only cool,but technically useful.
