Spend a bit more on a GPU if you make these changes (go for 950/960 or 380);
You don't need a Z series motherboard for that chip, the chip is non overclock-able, unless of course the z97 is cheaper. then go for it.
PSU seems ok from a google search
RAM is fairly good
Hard drive is good, if WD is cheaper go for them, i havent had any issues, but maybe someone can vouch for seagate
Case is ok
CPU should be fine
LoL should run great
