well it would not take a long time couple of hours depending on what you want as for suplies it depends on what you want to build i would recommend building this one http://www.freewebs.com/crossfireenclosures/ but you would have to resize its 4x2x2 it is melamine so you have to be carefull with it and predrill evrything as it can crack and it would be really heavy this is what im going to build you could use ply wood but certain types are dangerous for beardies pine and another that i know of use that site for help on building as you can use almost any material you want for it you should look at the great list of enclosers for ideas it on here somewhere well thats all i got hope it helps
