Wayne;Thanks for the 2 Pi Tower plans.
Went to Home Depot and had them cut the 3/4in MDF according to the plans - charged $.50 per cut - simplified this project significantly. Will enlarge the port 1/8in to accomodate the width of the MDF. The port diameter may have to be further increased due to bracing (resulting in decreased internal volume).
Will be ordering the kit once I have the cabinets staged.
