Hysterisis - a new computer case design in process

This is a new case design I'm working on in the studio. The piece shown here is a plaster casting with shellac (and some filler). I am nearly ready to take a silicone mold of this piece. the final version will be a resin casting. I'm trying to work out a suitable composite of fiberglass and epoxy. I have also purchased some powdered copper, which I am excited to use in the mix.

Hysterisis is a term that is used in electronics to describe the difference between the switching threshold from when the signal is rising and when it is falling. This is an important characteristic for any circuit that takes input from a varying source and uses that to decide to do or not do something. A pressure switch on a pump or a thermostat on a heater is a good example of this. A schmidt trigger is a common electronic circuit that exhibits hysterisis.
