Since LaunchBox isnt really "installed" but Located, best would be to put it on a internal sata hdd 2tb / 3tb, and add as much RAM as possible, i have a Ryzen 3 2250g, M2.ssd-240g, 8gb ram, and now a GTX-1050, with LaunchBox on the D drive (normal 2tb sata6)
I am going to up the ram to 16gb or 24g, if you want to cache the images faster, as for anything else the 8gb of ram was fine
