Art Nouveaux Case Mod, Part 2

The Side Panels

With the front-to-back dimensions now known, I could start work on the rest of the panels. A simple bottom panel is cut and the edge routed to extend slightly below the side and front panels. The base is necessary to support small feet at the corners which will raise the system above the desk or floor surface.

Two different side panels with windows are planned, with an intricately detailed one on the motherboard side. The other case panel will also have a window treatment, but not as detailed. There is a motherboard tray that slides into the bottom of the case, and behind this is a sheet metal shield, placing little or nothing of interest in view through a window in that side panel. I am thinking that the sheet metal may allow for some specialty backlighting in this narrow gap that should show off a second art glass window really nice.

Using a high-speed rotary bit in a Dremel tool, the smaller openings around the flowers are enlarged and cut to shape. Using a selection of different shaped burrs in a flexible shaft, the curves and blossom details are roughed out. After that, it's more carving, lots and lots of sanding, and finally - sealing of the wood. Then, the whole process is repeated with the second side panel.

To hold the wood panels to the case, they will be attached to the original sheet metal chassis panels with four or five screws. Before final attachment of the wood side, a custom window hole must be cut in the metal panel to allow light to come through the windows.

By attaching the wood to the the metal panel, the edges of the carved openings can be scratched onto the painted surface of the metal panels. The incomplete pattern of outline scratches is completed in a connect-the-dots fashion, to create the guide to cut a window opening. With the outline now clearly marked on the painted surface, the wood is removed. The metal panel goes outside for a close encounter with my handy-dandy plasma torch, quickly cutting out the window openings.

Next time: The top panel and front door.
