No exp with that tank, but 20 gal AIO is a nice size. I have a IM20 with low-iron glass. The starphire glass should look great, but be careful with the velcro-type algae magnets and frag racks.
I seen one all set up in person the other day. it looked really nice! I felt like buying one too until I stumbled on a deal for an IM50. if it wasn't for that I would've bought the waterbox.
