Why not consider going even larger on the chassis?
Ok Aaron, you win!!! I have played around with the top plate size and it looks, to me, like 10"x14" is close to my "ideal". It will give me some room to maneuver and accommodate the bigger, heavier iron. I like the visual esthetics of the top components and I gain ample real estate in the basement!!
I have ordered 0.125" aluminum plates in 10" x 14". This is just over 50% thicker than the stock chassis plate. Again, better for the longer span and heavier iron!!
I got some board assembly done this weekend!!! Getting excited!!
Cheers,
Geary
