Overall that is an OK build. You have some overkill going on in the storage department with $1100 tied up in it . Thermal paste is not needed with the Noctua. Motherboard is overkill as is the PSU... There are better options for a HD than Toshiba.. I would do something similar to the build below if I had that kind of budget (and tried to kept plenty of storage). Note the dual 4k monitors instead of a single 2k.

Well I am actually going for 1440p, as I can't seem to achieve very high framerates at 4k, even SLIing one of the most powerful cards in the market right now, so I'm going with the 2k 144hz monitor and just sitting with that until GPUs can meet more demanding games at 4k.
I went with Toshiba because I've read that Seagate HDDs have a high fail rate.
And I see what you mean about the Thermal Compound, I'll take that out.
Is there anything bad about overkill? Like a long-term detriment to a build?
