I got the top and back all skinned with OSB and got the dummy drawer replaced with a real one. Lots of room here.

Haven't got new pics but I have a power strip mounted on this end and a tool/screwdriver holder bolted to the other...

I added verticle risers to each corner to strengthen those to better carry the load.

I picked up a piece of 1/4 inch HRS today 24" x 54" to use as the top. I will be adding some 2 x 6 risers to the top, standing on edge, to raise the work surface up to my level. I will inset them from the edges of the base cabinet a couple of inches which leaves lots of room for clamping to the edge of the 1/4" top plate.
Another addition I am thinking about is adding some slide out shelfs to the two end doors.

The doors are all 9" wide which just fits the width of a plastic shoe box. If I put a few boxes on the slide out shelving I can keep a lot of my grinding discs and sanding pads right there in the cabinet. The middle doors will be for grinder and sander storage.
