Oceanic 30 Cube

Can anyone tell me if any of the sides are NOT tempered and drillable?

I have an Oceanic 30 cube and the back is definitely drillable, I put three holes in mine. I think it's a pretty reasonable assumption that all side/front/back glass is the same, there's no reason they would use different glass on different sides. The bottom could be tempered though...
