All my desktops are self build, don't know what that has to do with my opinion about older amd pre zen, and celeron cpu's. The i7 8700 is made from reclaimed hardware, except the cpu cooler. Only the laptop/tablet = transfomer book is a branded system and came with 8.1 x86 Home pre-installed, it has just a 4 core atom cpu and 2GB Ram with a slow emmc 32GB drive and runs x86 19045.5737 now, it had no problems with installing the lcu.
With branded I mean from a recognised OEM like HP, Dell, Asus, etc, these products are very expensive and doubled the price of assembled PC in Argentina
