+1 on external i did it on my 50 cut the notch myself not too hard just keep the bit wet i love the extra room inside the tank. if i can figure out a way to do external on my future 120 i definately will.just means i have to cut a hole in my wall which i am ok with .... the wife not so much. so i may have to go internal. which is still better than hang on back which is what im currently using
