The case is the easiest and cheapest part of the DIY Laptop. There are many good options, from 3D printed, plywood, acrylic, CNC aluminum, fiberglass, a briefcase, even clay, paper mache or lego. The cost will be <$20, no matter what.
The lego case is most DIY, modular and open source. It is only option that can be freely disassembled and reused. The mechanical properties of the lego are same as 3D printed ABS or ABS injection molded cases. The reproducibility of lego cases is high. If more strength is needed, the lego can be glued.
Plywood or acrylic are strong and cheap case materials. They can be lasercut.
Aluminum is an ideal case material, because it is strong, durable and light. It needs machining. Titanium is better than aluminum, but more in cost.
3D printed PLA or ABS plastic will make a case that is not as strong as plywood or aluminum, but can be made using only a 3D printer.
Fiberglass or carbon fiber is a high performance case material. It will make a very light case. Construction is slightly more difficult than the other options, as reproducibility is less.
A briefcase or binder can be made into a laptop case.
Clay and paper mache are the most DIY options.
