That kind of looks like the same sort of set-up that came with my Ryobi BT3000 saw a long time ago. At first, I thought it was a great idea because it saved so much space. The main reason I quit using it as a router table was the ribbed aluminum top which works well when feeding wood straight into a table saw blade made maneuvering irregular shaped pieces into a router bit a little difficult at times the edges would dip and catch into the voids in the table surface. If you have a chance to see it at your local sears store, take a scrap piece of wood and see how well it slides across the surface.
Another thing to consider, how does the unit attach the router to the table? It can be a real pain to switch from above table work to below and back if you only have one router.
Just my humble opinions,
