Hi Frank,
Thanks for the detail on the G3 Plus. Your experience with DDR4 vs. 5 matches mine; DDR5 is not a top priority at this time. Great to know the 2280 slot supports both PCIe and SATA.
Just realized another advantage of the G3 Plus is socketed RAM instead of soldered (32GB max.). GMKtec sells a barebones model on their website for $119.
