*table saw/circular saw
*jigsaw/router
*yardstick/tape measure
*GOOD box plans
*MDF
*plain old elmers wood glue, or titebond II if you want; stay away from liquid nails or gorilla glue. while they aren't necessarily bad, they are better, cheaper(the wood glue) alternatives
*some 1.25" drywall screws (if ur wood is 3/4" thick)
*clamps help, but aren't necessary. using screws does fine.
thats really all it takes for a plain, basic box.
of course, you can spice it up with various router bits and the like
measure twice, cut once.
