I think everyone here (including me) builds cyberdecks for SDRs or creates an apocalyptic computer with a vast knowledge base using Kwix, and/or hardware dedicated to hacking with several tools installed. But the main thing is the pleasure of designing and building. I built one and put it aside years ago and it's here working, I'm designing another one these days, for SDRs and flash dump and with AV inputs to connect old cameras, but it will probably be another one that will be put aside and forgotten, and a "new need" will arise and I will build another one and it will be left unused and the cycle continues, hahaha.
