Always liked having the cabinets on casters.
Oddly... it Seems to cut down on that gravity field that makes tiny screws bounce under neath them when you can actually get your hand underneath there to recover the screw!
Without an off the floor gap, It seems to create a Hyper-space portal that just sucks tiny stuff in at a velocity beyond any human eyeball tracking abilities!
...still never have figured how the damned dropped socket will always roll, up hill, to the middle of underneath a vehicle though.
