Is this build going to be good for gaming for the foreseeable future?

you can take regular trident z 3200 mhz ram, and a regular cryorig h5 cooler, but I also like the looks of this build and the performance difference is mwah 3-5% worse?

Sometimes there are RAM clearance issues with the H5 Ultimate. The Thermalright Macho Direct and Scythe Mugen 5 Rev B are better performing coolers without the clearance issues and about the same cost. The Cryorig H7 Universal is slimmer and doesn't have clearance issues. Performance is similar to the Ultimate.

Otherwise it is a good build.
 
Made a few changes. :)

Their not memory clearance issues with the memory he or I listed.
 


It would be a very tight fit. The Cooler is 160mm to 168 mm tall depending on fan adjustment height. The NZXT S340 accomodates 161mm heatsink height. The RAM clearance on the H5 Ultimate is 30mm to 35mm (depending on fan height offset). Both Corsair Vengeance LPX are 33.5mm and Team Vulcan DDR4 are 32mm based on the specs I could find. Going by those specs that cooler would be 162mm to 163.5mm minimum but could end up being an mm or two higher to accommodate the RAM. While the heatsink may fit over the RAM. It would go beyond the case's cooler height. Perhaps the case has a little extra room. I wouldn't risk it.

The Thermalright Macho Direct is 158mm and the heatsink is offset to avoid RAM clearance issues. The Scythe Mugen 5 Rev B is 154.5mm and offset as well.
