Additive Drive Storage System

External Drive Storage for use as Direct or Network accessed devices. Stack-able Trays Interlock to allow expansion. This is designed to be a NAS box. Tray cases accommodate Optical drives as well. Each Tray can hold one 3.5 inch hard drive or two 2.5 inch hard drive using the Insert trays or one optical drive. Simple Faceplate door incloses and locks the Hard Drive tray in place. I'm uploading basic bottom and top covers since I have not yet finished the Power and Electronics trays. I will upload my thoughts and designs for the electronics on a separate "Thing" upload, things like Mini ATX board or Sata Port Multiplier and even simple USB Adapters with USB HUB. Let your imagination flow!
