suggestions:

- microatx pc, can fit full size gpu and microatx mobo, full size psu, also many fans, good ventilation, upgradability very good..

- find any good SFF cpu, for eg dell optiplex 7010, im using one..can find one with i7..can put up to 32gb ddr3 ram, ssd, hdd and low profile gpu 1050 ti...drawbacks less choice on gpu and ventilation not so great..

other than that..no idea..maybe others have experience..
