   I'm   
   trying to stick with standard, off-the-shelf plug in commodity   
   parts.   
      
   ----------------------   
      
   My system is off-the-shelf except for solar battery charging which is only   
   slightly custom, mainly adding breakers, fuses and meters in boxes and   
   interconnecting them. I couldn't find DC substitutes for everything so the   
   computers all normally run on grid power without a UPS, as I estimate the   
   depreciation cost of cycled batteries to be higher than the grid per KWH   
   consumed. The laptop's batteries act as a UPS for themselves and USB-powered   
   external storage. 10 minutes of remaining battery life is enough to switch   
   to the UPS when the grid fails. They are the thicker and heavier   
   desktop-replacement business models that accept second internal hard drives,   
   so they have an SSD to boot from and a Terabyte HDD for storage.
