Very clean construction.
I have a question: since you have the base on wheels, all of the weight (cabinet + monitor + etc) must be supported by the base; how are the sides attached to the base?
I'd like to do something similar, but would like to attach the screws holding the sides from the inside, to avoid using woodfiller (the outside will be a natural finish). I'm concerned that the screws won't be long enough/strong enough to support the weight of the cabinet.
Thanks,
