I tried to look around the interwebs on it, and it seems that the curved piece is definitely tempered glass, but no mention of the back piece. It seems that the brand Jebo, is also re-branded into SunSun, LAC, and others.
Why not just run a CPR siphon overflow down to a sump and skip the drilling all together? Modifying the hood doesn't look too difficult since there are already cutouts for plumbing back there....at least that what it looks like in the last picture of the first post. Or take the top off all together....
