If you can give the otion to replace like graphics cards from 2 radeons to maybe 1 GTX card this would increase the flexibility of the way you could build your pc. Also maybe HDD and SSD should be replacable by other marks like seagate. and towers should be adabtable towards making them cooler or bigger like a mid-towder a small tower or maybe even a rack for a server or so. Contact me about this any day you want because its vacation for me and i have all the time i want.
