Building a quiet gaming system is something that takes a surprising amount of care, owing largely to smart choices in component selection and often careful tuning. The last time we checked in with AVADirect, they for the most part had the balance down with the exception of the NZXT H2 enclosure. We liked the system overall, and the revision of the H2 helped to alleviate some of the enclosure's airflow issues, but it wasn't what we were looking for in a high end, specialized configuration. With our third go, it looks like that problem has been eliminated. Sort of.

In the NZXT H2's stead, AVADirect has sent us the much beefier and more respectable NZXT H630 along with updated internals. They've also taken some care in not just configuring, but rigorously tuning this build, and as we go on we'll evaluate the fruit of that labor.

Honestly it's pretty hard to find too much fault with what AVADirect has done here, at least in terms of component selection. There are going to be aspects of this build that will be matters of taste, but this build has obviously skewed in favor of performance over absolute silence. That's totally fine; it's "Quiet," not "Silent."

The Intel Core i7-4770K is at this point a reliable workhorse, the fastest CPU you can get for most practical purposes. AVADirect has given it a modest overclock up to 4.2GHz with 1.28V on the core, and it idles down to 800MHz and ~0.72V like it's supposed to, so no complaints there. Strapped to its integrated memory controller is 16GB of low voltage DDR3-1600, CAS 9, courtesy of Kingston. This is pretty standard, but I'd've actually opted to make the move to DDR3-1866 for a performance system. Ian has handily demonstrated that DDR3-1600 is no longer really the sweet spot for Haswell.

Handling graphics duties is the Gigabyte WindForce 3X model of NVIDIA's GeForce GTX 780. A custom version of AMD's Radeon R9 290 or 290X would possibly be more ideal, but with cryptocurrency substantially disrupting prices on AMD's high end, the GTX 780 really does strike a strong balance, offering excellent performance.

I'm a little more fussy about the storage subsystem. I like the silenced enclosure for the Western Digital Caviar Black, but the price premium on that coupled with the drive itself suggests that just going with a 480GB SSD for not too much more money might have been more ideal. The two Kingston HyperX SSDs in RAID 0 are cute, but striped RAID on SSDs serves no real practical purpose except to boost benchmark scores. This probably could be more optimized; in the future I'd almost suggest opting for a single ~1TB class SSD.

    Dustin, thank you for the review. Regarding rubber fan mounts, why are screws preferred?
  • Samus - Sunday, February 23, 2014 - link

    So your fans don't fall out.
  • tim851 - Sunday, February 23, 2014 - link

    That only happens with shitty mounts.
  • homer_pickett - Thursday, October 9, 2014 - link

    +1 to keep the fans in place. /Homer from

    The fans installed in this system have a built in rubber bushing so you don't need to use rubber mounts to silence them.

    Rubber fan mount always leave a little crack between fan and case, which is a very severe air leak that will cause inefficient air cooling...

    Neat I guess. I have a chub but not a full on erection.
  • xaml - Saturday, March 1, 2014 - link

    @Gyro231995 What you're really saying is that certain people and their bushes should be thrown into oversized fans. I couldn't agree more.
  • brucek2 - Sunday, February 23, 2014 - link

    My first reading of the table was that this was a system that included 3x Nvidia 780s, yet was still quiet, and that cost only $2,500. I was ready to order on the spot.

    The downside of that much excitement is that now that I've realized its just one, it seems so so much less interesting.

    I thought the same thing at first. I know avadirect has a good price point but damn that would have been a sweet deal.
