I'll try to help, but I concur: nothing great so far, so much hype.

Acer B276HK 27-inch 4K IPS display
Kingston SDHC UHS-I Class 3 flash cards 64GB $43.99 32GB $23.49
Crucial MX100 SSD 256GB $79.99 512GB $159.99
Joby GP3 GorillaPod SLR-Zoom Flexible Tripod + BH1 Ball Head with Bubble Level $36.99 (59% off)
Fine build, however, I really recommend going with an SSD over the HDD, especially of you're gaming. They're more expensive but well worth the investment.
This one is half the size at 5x the price than the SSD you chose, but you'll enjoy super-fast to virtually no loading times.
