It measures 86.3 × 38 mm and has 4 copper layers, 4.69 mm thick.
36 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Sasasu/DellPSU2ATX repository on GitHub, at the commit this page was made from: the board is DellPSU2ATX.kicad_pcb and its schematic DellPSU2ATX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Sasasu before reusing the design.
