Ok guys I have begun the journey into rack building. I have 5 snakes, so its a small rack designed for 5 tubs, or 4 tubs and a tank on top for aesthetics. I bought the supplies, and I unfortunately went the cheap route and chose 3/4"particle board over melamine, which is curing right now with polyurethane sealant, but I think Ill be alright based off of everything I read on this site. So anyway here is what I have, and pics will be up after I am done.

6 shelves 29"x17"
1 back 17"x35"
2 sides 29"x35"
5 Sterilite 1926 tubs (34qt/32L)
6ft 11" Flexwatt
3 6ft Extension Cords to be split and spliced for Flexwatt
1 Herpstat proportional thermostat
5 Thermo/hygro
1 qt Polyurethane coating
Extension cord, water bowls, newspapers
