While that box could probably be done with a router (simple table would help), jig saw (for roughing the big openings), and a hand drill--Stick probably has a realistic list of what happens when one starts down the "slippery slope". He left out the sanders/scrapers.
It's a great hobby, and probably cheaper than some hobby. Not sure which hobby, but there must be one!!
Good luck on the box build!! That's a pretty intriguing idea--and there are a few woods that might add a pleasant odor for a while too...i'm thinking cherry with the heat from the power supply might be something of an air freshener for a few months.
