Coolers are very easyto set up.
Once you find a cooler that fits your need size wise make sure it has a good seep on the lid. Most people will use a marine cooler or a Coleman xtreme.
Once yOu pick up the cooler you need to buy beads or whatever you are gonna use for humidification.
If you go with beads you can use this site to find out how much you will need.

Once you get the beads then you can rinse the cooler out and let it dry out to get any "plastic" smell it might have. After a rinse and dry throw the beads in the cooler and a hygro in there.
Now you can buy Spanish cedar trays or just use old boxes to store singles and take up some room. If you go to walmart or some large store like that you could also just pick up some cheap plastic trays or bins also.
That's about it for coolers.
1.buy cooler
2.rinse cooler
3.add beads (or other form of humidiy)

Simple.
