I am about to build my first 60% keyboard with the gh60 pcb, in this venture of gathering information and parts overtime I decided i want a very specific layout as in the image below (ignore the allocated letters and modifier keys). The gh60 is unable to do what I want in the bottom spacebar row, so I was wondering if there is a pcb around $40 that I can use for my desired layout, and if there is a site I can purchase a 5u spacebar from. Any help is appreciated, thanks.
Also not necessary but I do kind of want a pcb with built in ps/2 support.
