Large table that you can walk around. Towels over the surface. Lay the parts out around the chasiss as they came out of the case. Screws the same way.
Goes back the same way it came out.
Why the towels you ask? Well I'll tell you. When you drop a itsy bitsy, teeny weeny, microscopic screw that's an odd metric size and left threaded to boot, you'll find it the towel quicker and surer, than you'll hopelessly search in the carpet for. Besides it doesn't bounce off the table and do a short tap dance on the grill before diving in to the floor vent.
That sound would make Chuck Norris cry...
