personally I would leave enough room to slide a 55 gallon tank into the stand incase you decide to run a sump someday. Otherwise that looks like a pretty nice stand so far.
some updates on the setting up
so far i almost have all the things i need to set up just need to finish building the stand. havent had anytime or money lately cuz most of the time i spend now is with my Girlfriend and also most of my money so i just bought myself 2 36inch t-5 HO lights for the tank. i still need to buy an fx5 but might get it for my bday since its a few days away. i also need to buy 200lbs of gravel and gotta stain the stand and start on the canopy. but 80% of all my money is being spent on my GF or college and then i gotta pay for gas and soon i gotta buy new tires so that leaves me not so much money for fish
here are a few pics of the lights i bought and an update on the fish that are gonna be in the 210 and i also bought an amazon sword plant that will go into that tank as well
You should really make room to allow a sump...
I have the same exact tank as you except mine is drilled w/overflows, and i plan on running at least the FX5 an AC110 (both of which are currently on my 90), and a sump too.
