Here are some hints and other ideas.
* Prefer 3/4-inch plywood to MDF or particleboard -- especially where you're fastening the rails -- becuase plywood holds screws much better and it's much more resistant to sagging.
* Remember that 3/4-inch plywood is acually 23/32 inches thick. Most other sheet goods are 3/4.
* Office desktops are typically around 30 inches high, which can be uncomfortably high if you're in a typical chair and doing a lot of work with something placed on top of the desk (like a mixer or keyboard). So, consider the height of the equipment you're working and the chair you want to use with when planning the height of your base cabinets and desktop.
* Google recently acquired a tool called SketchUp which is free and may be useful in designing and visualizing your workstation.
* Before you cut any wood to make racks, be sure the rails you have are compatible with the internal width you plan to use for the rack gear, and adjust any measurements on your plans accordingly. (e.g. 19" might work, but 19.125" might work better.)
* Remember to allow easy access to cables if necessary.
* Plan for cable paths by installing gutters, drilling holes, etc, so you can run all the cables you need to run.
* Remember to install support for extra heavy gear, even if it's installed in rack rails, which typically only support the front of the gear.
* Prefer steel rails to wood (or milk crates)
* You might find it easier to pre-stain the wood before you start cutting and assembling it.
* Use dado and rabbet joinery if you have the tools and skill. Or if you use butt joinery, be sure to use dowels or biscuits. Use fresh wood glue.
* Remember to build it in pieces that will fit through your halls, turns, and doorways (!!!) and assemble in place if necessary.
* You can save a lot of cash on the wood if you're planning to paint instead of stain.
* I've found great deals in the past on long rails, which don't sell very well, but also don't stand up very well to a sharp hacksaw!
Hope this helps!
