I found this cart fairly easy to put together, however I'm not using it under the desk, I'm using it along side the desk.  I've got an Epson WorkForce Pro WF-4630 sitting to the right of my 29" monitor so my space is severely limited with the printer currently on top and in order to get more organized I got this to allow the printer to sit along side the desk instead. It also looks great with the desk as the base cabinets to my desk are also black. It also works out great for eliminating the space I need to put my reams of paper as it has plenty of room for them as well along with space for my other office items.
