Wow so after browsing Digikey for a while, I'm floored by how much stuff they have.  Do you recall the product ID or the size/dimensions?   I figure it will need to be at least 9x6x4, but I don't see your project box in the catalog.  Thanks again for the help.
EDIT: Also, are those standard sized buttons? (i.e. Happ/Ultimarc)  The box looks 4-5 inches deep including the lid, but it's hard to tell.
