Buildapc

I grabbed a copy of the "High Refresh Rate Build" from PCMasterRace and wanted feedback.

I've not built a new PC in many years and last I heard was the NewEgg was trash and unreliable now. Is it decent again, or is it worth paying more to get it elsewhere?

Also, is there room for more storage? If I bought two of the SSDs, would there be room?

Other components decent?

And, finally, my so wants an RBG case, so any recommendations on one of those that would fit this stuff would be great.
