Well probably the biggest concern in this tank is DONE!!!! Some of it went well, and other.... well you'll see.
A couple months ago I was asked to do a job with these sheets of marble to do a tub surround. The sheets came 24" X 84". Well to do a 5' tub wall one of those sheets had to get cut in half and look like a factory cut. So I got me one of these:

Cut that stuff like butter, so I thought, "hey, I wonder if this would cut glass?" Does it ever
So to start I cut 2 - 1 3/8 holes. I was told to cut 1 1/2" but I didn't have one and figured an 1/8" ain't gonna make a difference. So 2 holes on either end with the wife pouring water on the bit while I drilled and presto, hole on the left:
and hole on the right:
That was the easy part. So in part to procrastinate a bit more, I prepped the side panel so the base of the saw wouldn't scratch the glass:
At this point the wife couldn't watch so she went back upstairs and turned the TV really loud. Not sure if that was to drown out the noise of the saw or so she didn't hear my screams if I screwed this up
10 min later and 30 gallons of water spray later:
And the tank:
