We’ve been staying on top of sales round-ups lately, and noticed that several of our choices in our Best Cases of 2017 content are now on sale. This includes the Meshify C, Define C, Corsair 570X & 270R, Thermaltake View 71 & P5, and a couple of NZXT and Rosewill cases.

Rosewill's Cullinan PC case is the company's most modern endeavor since the R5, and manages to get to the front of the case industry's current trends. It's a mid-tower with a PSU shroud and a full tempered glass side window, which is checking almost all the boxes created by NZXT's H440, In-Win's more expensive cases, and Corsair's 760T. The only 2016 trend missing from the Cullinan is a set of RGB LED fans, but they've still got blue LEDs.

We first saw the Rosewill Cullinan mid-tower at Computex 2016, but the case was impacted by shipping delays (and other internal delays) that pushed back its launch until now-ish. In theory, the ~$150 Cullinan will begin availability just before October, and should begin shipping to customers by the first week of October. That long lead-in to production has allowed competitors to enter the growing market of cases with tempered glass side panels, including Corsair with its brand new 460X, In Win with its 303, and Anidees with its identical AI Crystal ($150).

The Anidees AI Crystal and Rosewill Cullinan enclosures both boast 5mm thick tempered glass side windows and a 4mm thick tempered glass front panel. The enclosures target the front edge of a trend in the industry to adopt tempered glass on affordable cases (read: ~$100 to ~$200), replacing the cheaper acrylic that's found in almost all windowed panels. Rosewill and Anidees both use Chinese OEM designer Jonsbo, whom we believe to be a customer of case factory God Speed Casing. If that name's familiar, it's because God Speed Casing is the manufacturer used (and effectively grown) by NZXT; we've even toured their factories in China.

This week's news announcements include AMD AM4 Zen chipset naming (rumors, technically), NZXT's new RGB LED 'Aer' fans, and a pair of cases from Rosewill and Cooler Master.

AMD's initial AM4 chipset announcement was made at PAX, where the B350, A320, and XBA300 chipsets were announced for mainstream and low-end Gen 7 APUs. The high-end Zen chipset for Summit Ridge was concealed during this announcement, but is now known to be the X370 platform.

X370 will ship alongside the Summit Ridge CPUs and will add to the lanes available for high-speed IO devices, mostly SATA and new generation USB. Most of the IO with the Zen architecture will be piped through the CPU itself, with what remains of the chipset acting more as an IO controller than a full chipset.

It's been a number of years since we were thoroughly impressed by Rosewill. The Rosewill R5, made back in 2012, landed on our bench as one of the best cases we'd ever worked with. It was exactly in-tune with the market, and shipped at a time when things like dust filters were getting hugely popular and common. Since then, the Throne filled a gap at the high-end, but not much else has caught our eye.

Finally, Rosewill's started making moves in the right direction (following the Gungnir launch). The new “Cullinan” case keeps with the industry's move toward the tinted, tempered glass aesthetic; Rosewill's using a high-quality, thick tempered glass side panel on the left and right of the Cullinan, and also throws one onto the front. The front panel, as one would expect, reveals the 120mm fans seated within the front of the chassis. Three were installed at the show, but we're told to expect somewhere around 4-5 total fans (stock) with the system – that'd be one in the rear, one or two in the top, and two or three in the front (all 120mm).

The mid-tower ATX market seems like it's burgeoning with options right now. Everyone's got some kind of mid-tower-with-shroud available, and those who don't already have one on the way. Of late, we've looked at the NZXT S340 (arguably the start to all this), the Corsair 400C – a good progression, Phanteks' disappointing P400, and we'll soon look at SilverStone's RL05B.

All of these cases seem to fall within the $60 to $100 range, too: The NZXT S340 is $60-$70, the Corsair 400C is $90-$100, the Phanteks P400 is $60-$90, and the Gungnir is a flat $65. SilverStone's forthcoming RL05B will land at about $60.

For today, we're reviewing and benchmarking Rosewill's own mid-tower gaming case, the “Gungnir.”

It's been one case after another lately: The Corsair 400C, NZXT Manta, Revolt 2, and now the Phanteks Eclipse P400.

Phanteks' Eclipse P400 is immediately reminiscent of the NZXT S340 enclosure, which we've pinpointed as the origin of the industry's obsession with PSU shrouds and limited drive support. That's not to say there can't be multiple products in the category – it's good to see continual innovation atop well-founded concepts, and new competition drives development further.

The Phanteks Eclipse P400 ($70 to $90) first entered our lives at CES 2016, where we got hands-on with its significantly larger convention sibling, the Project 916. The Phanteks Eclipse P400 review benchmarks cooling performance, looks at thermal walls, ease-of-installation, cable management, and overall value of the case.

Teased at CES 2016, Corsair's 400C ($90) enclosure swiftly followed the chart-topping 600C, a case that dominated our GPU cooling charts. The 600C and 600Q cases instituted an inverted motherboard layout – rotating and flipping board installation such that the GPU is oriented “upside-down” – but stuck with tried-and-died optical drive support. To allow for an enclosure more fitting of the “mid-tower” form factor, Corsair removed the 5.25” support in its new Carbide Series 400C & 400Q cases, shrinking the height from ~21 inches to ~18.27 inches.

This review of the Corsair Carbide 400C benchmarks cooling performance for CPUs and GPUs, all accompanied by build quality and installation analysis. The 400Q is more-or-less the same case, just with the window removed and sound-damping material added.

Rosewill had a subtle offering at CES 2016. The case & power manufacturer brought along its recently released full-tower, the Nighthawk 117, and announced the release of a new mid-tower case, the Gungnir. There were also a few minor updates with fans and power supplies that we'll mention at the end of the post.

Released 12/14, the Nighthawk 117 ($115) is the full-tower hybrid of the Throne and the Thor v2. The prominent, adjustable ventilation on those two cases is carried over to the Nighthawk 117. On this new case, Rosewill chose to go with two “click-type,” integrated fan controllers versus the rheostat-types after listening to user input. Other measureables include a top-mounted hot-swap drive bay, 4 x 5.25" drive bays, and 8 x 3.5" drive bays. All of the the 3.5" bays are oriented left-to-right for easy access. The top five 3.5" drive bays can be removed via two thumb screws to increase air flow. The Nighthawk 117 fits any ATX form factor motherboard and has the standard bottom-mounted PSU location. For cooling, the Nighthawk comes with 5 x 140mm fans: 2 blue LED fans in the front, 2 non-LED fans in the top, and 1 non-LED in the rear.

Active users of the site will notice that we've gotten back into case reviews recently and, thanks to some new methods, we've gone a lot deeper with methodology than previously. The bench now includes thermal-over-time charts – which add great value to design analysis – and we've spoken with a number of experts on small design features to spot. Until now, all the 2015 cases we've looked at have been mid-tower or smaller. This B2 Spirit ($180) enclosure is a giant in comparison; in fact, it can nearly fit an entire NZXT S340 within it.

The Rosewill B2 Spirit full-tower case is targeted at gaming PC builds, but can readily fit server-class HPTX motherboards. It's got some unique design features, like pop-out fans and an elevated top-panel plate, but also has some unique oversights. This Rosewill B2 Spirit review tests case build quality, temperatures, and competitive alternatives.

The RGM-1100 is Rosewill’s latest mouse at $40, a successor to the RGM-1000 that we previously reviewed. The RGM-1100 is prominently marketed towards gamers in looks, packaging, and features. It is also an example of the market surge to implement RGB (or at least multi-color) lighting in everything possible -- headsets now included.

While the RGM-1100 doesn’t support 16.8 million colors or have a multitude of macro keys, it does have multi-color lighting, configurable settings, and adjustable weight.

This review of Rosewill's new RGM-1100 gaming mouse looks at endurance, button layout, sensor and acceleration specs, and value.
