I just acquired one but one of the side cracked in shipping. It's all plexi-glass and the side can probably be replaced. You can have it for nothing, after next week as I need to hold it for 5 days to collect UPS insurance on it. Just need to pick it up.
Angel, I have a friends fuge in my garage with a LOA 65w pc fixture. He wants $50 for it.
It is a 20gal long with a few glass baffles. The only thing with it, for a 125 you will evaporate around 2gals per day and the chamber with the pump only holds about 3-4 gals (depending on how high you run it)). In other words, you will have to add water manually all the time or have an auto top off.
Personally I would go with the biggest thing that you can fit. I just thought I would mention this fuge in case you had space restrictions.
