On this Part Picker List (https://uk.pcpartpicker.com/list/nTPq7h) it came up saying:

The ADATA XPG V1.0 8GB (1 x 8GB) DDR3-1600 Memory operating voltage of 1.5V exceeds the Intel Skylake CPU recommended maximum of 1.35V+5% (1.417V). This memory module may run at a reduced clock rate to meet the 1.35V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum.

AND

Gigabyte GA-B150M-D3H DDR3 Micro ATX LGA1151 Motherboard has an onboard USB 3.0 header, but the NZXT Source 210 (White) ATX Mid Tower Case does not have front panel USB 3.0 ports.
