Just order the new pc parts.what do you think about them?

They're fine, though the H100 and 680 are overkill (the $35 Hyper 212 EVO and $400 670 are better values).

The time to ask this question is BEFORE you order when you still have a chance to make changes.

My changes would have included:
1) Ditch the H100. It is expensive, noisy, less reliable, and does not cool significantly better than a #30 air cooler.
2) A 16gb kit is not necessary for a gamer. no game uses more than 2-3gb by itself.
If you do want a 16gb kit, make it a 2 x 8gb kit which is easier for the motherboard to manage.
3) The sabretooth is nice, but any Z77motherboard at half the price would have done as well.
