Roll around tool and fastener cabinet

I was tired of looking around for misplaced tools, so for Christmas I asked for (and got) a nice tool cabinet, nice and shiny in fire engine red. Then I got tired of misplacing my increasingly large collection of screws, nails, and other fasteners. I decided to make something that would hold all of this stuff in one place, and be mobile.
Materials: 3/4" MDF, poplar edge banding, 1 /2" caster wheels, two different types of plastic bins
Construction: dados for shelves and verticals, edge banding glued and nailed with brads
Finish: two coats water based polyurethane, red enamel paint for sides and accents
