Introducing the Serenity Box. The worlds first fully disassemblable carbon negative PC case. The Serenity box successfully asserts itself as the most sustainable full-sized PC case on the market. It has done so by being made entirely out of timber parts, with the exception of sub assembly fastenings. Thoughtfully designed in the way of Design for assembly and disassembly, The Serenity Box can be entirely assembled and disassembled with a single screw driver. This ability makes it not only more sustainable as it can be disassembled easily for reusing and recycling but it makes it functionally superior and according the an expert PC case builder, easier to work with and more convenient than any other cases commonly used by experts. The live hinge outer shell coupled with magnets provides a unique Toolless entry that is both functional and aesthetically unique; this means that even once assembled the Serenity box can be easily upgraded or shown off. The live hinge is also incorporated inside the case providing a creative never before seen cable management solution that maintains a functional but also uniquely aesthetic look that ties the external design to the internal design. The dimensions of the case mean that all standard parts including the largest consumer grade PGU, the Nvidia 4090, will fit into the case. The manufacturing combination of CNC and laser cutting means the case can be kept for a very long time as even if mounting standards change the Solid timber exterior could be kept while the laser cut plywood mounting plate could be swapped out to make way for newer components. The Serenity Box successfully fulfills the established criterial of making a PC case that is more functional, more sustainable and aesthetically unique PC case made out of timber.
