Hmmm, I'll have to keep my eye out. I usually don't really pay attention to the tank stank itself. Mine is hideous right now, I have just the custom 2x4 frame in my living room. The tank was getting too hot so we pulled the entire shell off the frame to allow more air flow under the tank. I don't even want people in my house right now because it looks so bad! I can't wait for our house to be finished so we can move out of this dreadful basement apartment.
Personally, I like the first molding better. I think it's a cleaner design and just looks really nice.
