Personal choice. There's absolutely no difference between full, semi or non modular other than looks and wiring capability. Non means all the wires are permanent, so any unused leads have to be found someplace to be tucked away, which some say is ugly, especially in cases with large side windows. Semi has full modular leads except for the essential power leads like the 20+4 pin and EPS. You will use those anyways, so modularity there is moot. Full just means you get to install the psu easier as the unit is placed then wires can be routed as needed instead of threading the entire 20+4pin and EPS from the start. Both modular versions have the benefit of removing the unused wiring, cleaning up the looks. With a solid side case, where looks...
