The build is not bad. there is room for savings though. Of course getting the z170 is your best bet, but if you don't plan on overclocking or dong anything extreme, then bumping down to a i5-6500/b150 could save some money. $90 for RAM is a bit too much for me, You can save $10 on getting G Skill, but nothing really major about that. There are cheaper motherboards (Gigabyte and MSI come to mind) with the Z170 chipset. And to save a quick $20, do you really need a DVD drive?
