During our visit to CES 2013, we had a chance to meet with Deepcool, a deceptively large Chinese company that has been producing heatsinks for OEMs for some time now. Deepcool is striking out with their own line of heatsinks targeting enthusiasts in the PC space, and they sent us a hefty box full of accessories and more importantly, a massive stack of heatsinks to test.

Tower coolers are pretty much the way to go these days if you're going to air cool your CPU, and Deepcool has a substantial number of them on offer. They also have availability virtually everywhere in the world except the United States, an issue they're fast ameliorating. The problem these coolers are going to face is a doozy, though: the heatsink industry already has a tremendous amount of competition. Does Deepcool have what it takes, or are they going to need to bring something more aggressive to the table?

Amusingly and appropriately enough, the wave of silence-oriented enclosures that have been popping up recently haven't really drawn attention to themselves as a trend. Yet all of a sudden, we have results from a couple of solid contenders from Nanoxia and a few less expensive (and more readily available) also-rans. For a little while, this was a wave that Fractal Design was riding high, but the Define R4 wound up being a little underwhelming. As it turns out, they might just have something better lying in wait.

We never had a chance to play with the original Fractal Design Define XL, so it's tough to draw a direct comparison there. Yet one look at Fractal Design's page for the original tells you that while the Define R4 didn't change much from the R3, the Define XL R2 is a major shift. The original XL didn't support E-ATX; it was more just a conventional Define with a separate drive compartment. This R2, on the other hand, really is a giant Define R4. As it turns out, that bump in size and modest increase in cooling capacity may very well have been all the Define R4 needed.

Just recently we had a chance to review Nanoxia's Deep Silence 1, arguably the most impressive silent case we've ever tested. Nanoxia was able to produce an enclosure capable of delivering substantial air flow to components while still containing fan noise. In a market where silent cases usually lose a lot of their luster once overclocking enters the picture, the Deep Silence 1 was a breath of fresh air and proof that you could build a powerful system that you never had to hear.

In a bid to capture some of that sweet, sweet boutique volume, Nanoxia has refreshed the Deep Silence 1 into a slightly less expensive enclosure: the Deep Silence 2. The DS2 is an odd bird; it's a trimmed down DS1, but not heavily so, and in certain ways it can feel like a refinement. That all sounds incredibly promising, but did Nanoxia lose some of the potency of the original chassis in the process?

When we visited CES 2013, it became increasingly clear that not only were closed loop liquid coolers here to stay, but that they are in fact "the next big thing" in desktop system cooling. There are good reasons to go for them, too. While you may have to deal with some mild pump noise depending on which model you go with, closed loop coolers are capable of providing excellent performance without creating a racket or placing too much stress on the motherboard (the way a heavy air cooler might).

That we have three new closed loop coolers available for review not long after the last roundup should tell you that the closed loop cooler market is, if you'll forgive the expression, heating up. On the heels of NZXT's Kraken X40 and X60, Corsair has their own H90 and H110 coolers based on the same Asetek 140mm and 280mm radiators. Our newer, potentially even more exciting competitor comes from Swiftech in the form of the 240mm H220. Unlike conventional closed loop coolers, Swiftech's entry uses high quality brass tubing and copper fins in the radiator along with their own specially designed pump and extra thick (yet still flexible hoses). Is it enough to shore up the difference between traditional 240mm radiators and monstrous 280mm ones?

The desktop enclosure market has broken down pretty simply into three categories with only the rarest of outliers. Cases under $100 will either have good acoustics or good thermals, but never really both. Cases between $100 and $150 will typically find a balance. And if you're paying more than $150 for a case, it needs to deliver on both, full stop. The problem that sub-$100 silent cases often run into is that the measures taken to keep noise down result in substantially reduced airflow, and when you start really pushing the hardware (and thus the limits of the case's cooling), those measures actually serve to increase system noise beyond a garden variety case.

With all of that information in mind, AZZA's $99 Silentium is entering a perilous market. The Silentium is meant to compete with cases like the BitFenix Ghost and the NZXT H2, offering quiet computing at a competitive price point. The problem is that when you're at the top of the sub-$100 market, you risk having to compete with monsters like the Fractal Design Define R4 and the soon-to-be-released-on-American-shores Nanoxia Deep Silence 1. Does the Silentium carve out its own niche, or is it fighting an uphill battle?

As NewEgg's house brand, Rosewill has been growing in very interesting ways. Being the house brand of a major electronics retailer means dipping your toe into a lot of different markets, and Rosewill has expanded dramatically, to the point where their products are starting to crop up on other vendors' sites. At the same time, those products are gaining attention in their own right. Rosewill's own Thor v2 may not be the best built enclosure, but it's a dynamite performer and can oftentimes be found at a bargain.

Rosewill has also been fairly aggressive about pursuing enthusiasts. It's not enough to simply have a product and offer it; you don't see Best Buy sending out Dynex or Insignia televisions to websites for review. There's also sweet money to be had in chasing mid-to-high end buyers, and that's where the Armor EVO comes in. The EVO is a fairly modestly sized tower capable of supporting E-ATX motherboards and promises healthy cooling performance. It also comes with an unusually optimistic MSRP: $119. Is it worth the money, or did Rosewill misfire?

It wasn't that long ago that we reviewed NZXT's shiny new Phantom 820, a case that apart from its high price tag and slightly ostentatious design was pretty tough to beat. The Phantom 820 was providing some best-in-class thermal and acoustic performance, and it was a shot fired squarely across the bows of companies like Thermaltake and CoolerMaster, whose respective Level 10 GT and Cosmos II suddenly had a new, less expensive case to worry about competing with. Yet when I visited NZXT at CES 2013, they already had a descendant of the 820 on hand.

The Phantom 630 is just a little smaller, a little more conservative, and a lot cheaper. At $179 MSRP it's still on the expensive side and is clearly an enthusiast case, but unlike the 820, the 630 is using an entirely new chassis built from the ground up. The 820 scored a Bronze Editor's Choice award, but as it turns out, it may not have been a flash in the pan. Once you take a look at the 630, you'll start to understand why I'm beginning to think NZXT is entering a new era and the competition needs to be on their toes.

Most manufacturers are quicker and happier to show us their medium-to-high end cases, but for a lot of users the case is admittedly a steel box they put their computer into. While I personally advocate spending up a bit and getting a quality case, the enthusiast looking to maximize the distance their dollar can go may not be willing to shell out for something big and fancy. For those users, there are cases like the Antec GX700.

When I saw it on display at CES, I was surprised at the incredibly low $59.99 price tag. Now that I've had it in house for testing and review, I see more of how they got there. This isn't necessarily a good or bad thing, but simply a fact of life when you're buying budget. Still, a case at this price point featuring a pair of 140mm fans, a single 120mm fan, a fan controller, and support for increasingly common 240mm radiators? There has to be a catch, right? As it turns out there are a couple of small ones, but not the ones you'd think.
