I think too much on the CPU cooler, the motherboard, the RAM and the PSU.
CPU is good.
CPU Cooler, go with the Hyper 212 Evo
See if there is a cheaper mobo that is still Z87
Go with 2 x 8GB sticks instead of 4 x 4GB.
SSD is good.
HDD... Think about how you are going to back up important data. Drives die, plan for the worst
PSU... Do you need platnium? Seems to be costing more than you need. Have a look, if electricity is expensive and you will be running this rig 24/7 then it might be worth it.
The others seem fine. This is based purely on specs vs cost. Do not edit videos or photos, hopefully someone else can chime in on this. Can you use GPU acceleration to help with rendering?
