Patrick started building his Proton Pack in September, 2014 using a shell and motherboard from the GBFan store.  All aluminium parts were made by CPU64, except for the PPD and Booster Tube made by Ejgunth87.  Real parts include the R-331 and R-701 Clippard valves, grey Raython crank knob, LC-1 Alice frame, and Nycoil tubing.  Electronics are by GBFans/spongeface.  The pack was completed in May 2020; almost 6 years after starting!  For more information see the build thread at GB Fans.
