Have one of these for sale.

Only difference is with mine one side is rounded off not square.
Currently in pieces in the garage. One of the screws wouldn't go into the hole when putting it together but the desk is still very stable (possible can be fixed).
These are around the $150 RRP. Selling mine for $50.
Pickup only due to weight.
Measurements and photos to come...
