Additive Drive Storage System Addition Power Bay

This is the Power bay additions/changes to the Additive Drive Storage System I posted. Replaces simple Bottom cover with an expandable locking Bottom cover. Replace simple Top cover with a larger case cover to hold a Fan with for Electronics, things like a Sata Port Multiplier or a USB Adapter with USB HUB. Still figuring out what would best suit my needs. Please come up with your solution and possibly post it for all of us.
