On the bottom of the tank there is a sticker that says.. this bottom is tempered glass for strength and reliability do not drill
to double check put on some polarized sunglasses and look thru the glass in the sunlight...the bottom which is tempered should have wavy lines...if the sides/front/bottom are not tempered then they shouldn't have wavy lines...
+1 on research...I would suggest you write down the process in stages then write out the steps of each stage to make sure you know what you are getting yourself into

For example, Stage I would be Basic Setup Stage 2 would be Water & Cycling Stage 3 would be stocking and care Stage 4 would be maintenance...
Basic setup steps would include stuff like
1) tank
2) leak check
3) stand
4) placement in room
5) type of tank- fish only, reef
6) filtration choice (sump, HOB, even canister filters)
7) other basic equipment- heaters, thermometer, power head, etc etc
One thing about this hobby I love to plan things out and research each step to make my decision...
btw...this was just an example off the top of my head...I have everything written down in a tank journal...
