My husband and I put together the Martha Stewart flat file cabinet today for our Glowforge. It was a beast of an assembly project that took us more than four hours. We made one mistake early on, so there is an unfinished piece visible at the bottom (the finished side is at the back), and we had a problem with one of the drawer pulls that will be fixable with a little glue. But even with those mistakes, it still looks great:
It just barely fit under the window between Tom’s desk and the wall. The wide drawers will fit 3 stacks of Proofgrade each without the dividers, or one or two with some dividers in place (with smaller spaces for tools and stuff as well). We expect that we will be able to store the necessary office supplies in the lower drawers so that there will be more space in his office now. The color seems close enough to the PG walnut veneer that I think we will use that to cover up the assembly mistake.
For anyone thinking of getting this unit, it seems pretty well-made and assembly is not terribly difficult, but be very careful with orientation of the first few pieces. 
The instructions say that it requires at least two people to assemble, and I concur that I would not want to try it by myself. Also, the packaging leaves many tiny Styrofoam dots all over everything - you will want a handheld vacuum as part of your workflow putting it together.
I can put the vent hose out the window myself by standing on tiptoe and leaning on the window sill, but it would definitely be easier with a small step stool in there.
This is an elegant solution.
