It's been quite a while since I had the opportunity to review a case for BCCHardware and I've passed on several other products in order to snag this one. The Rosewill Cullinan shows off what Rosewill is capable of - and they are capable of quite a lot. There was a time when Rosewill was considered to be an entry-level PC peripheral and accessory company, but in the last few years they have stepped up their game and the results speak for themselves. They now deliver high quality, affordable products that aren't just durable; they are very attractive as well.

There are a few companies that produce cases with tempered glass side panels, and they don't come cheap. Rosewill looks to be entering this market with a case that looks as good or better than the competition and comes in at a price that compares with more traditional cases. For the price point, I don't think you can find a more attractive case and we'll start by taking a quick tour of the outside.


First Impressions:

As you may have guessed, my first impressions are pretty good. The case came shipped in a double box with extra padding on all sides in order to keep it all together on the long trek up here to Canada. It was worth it. The case arrived in top-notch shape and is a beauty to behold.

I encourage you to click on the images to see the detail and the quality of the case all through this review. The images don't really do it justice, but we'll do our best to share. If this case is as functional as it looks, it could easily be a winner.


Closer Look - Outside:

The front of the case is gorgeous with the solid sheet of tempered glass, but there isn't really much to show off as it is just a piece of glass. As you can see above in some of the images, the case doesn't offer any 5.25-inch bay support. The rear of the case offers a lot more functionality however. The expansion and graphics cards are held in place by screws and then secured with a bar to offer even greater stability. This bar will also help keep the case a bit more rigid as the frame is quite light-weight steel. When the side panels are on, it is very stout however.


The case uses a bottom mounted power supply location and ports to run tubing out of the case if you are using external liquid cooling. There is enough space in the case though to put more than enough fans and radiators inside - but we'll get to that in a minute. The rear fan can be easily replaced and the case supports up to 14 cm fans at the rear. 


Top USB & Buttons
Magnetic Filters Tempered Glass


The top front of the case offers 2x USB 3.0 ports, 2x USB 2.0 ports, headphone and microphone jacks, power and reset buttons as well as a simple fan controller. This simple layout looks nice and doesn't detract from the overall simplicity of the case. The very top of the case (and the front, behind the bezel) uses magnetic dust filters that are easily removable for cleaning and function as good as they look. Also pictured above is the "Tempered Glass" sticker that can be removed after installation - or left to show off your 1337 case.

On the next page, we'll take a closer look inside the Cullinan as we open this sweetheart up. Beauty is only skin deep, so we'd better find out if what is inside matches the outside.

Closer Look Inside:

Once we drop the sides off the case, we discover that the inside is almost as clean as the outside. It looks a little odd honestly as there are no 5.25-inch bays at the top and you'll notice there are no 3.5-inch bays for hard drives visible either. This gives the inside a huge cavernous appearance. What you do get is an easily accessible spot to mount a triple fan radiator at the front of the case as well as a place to put a large 280mm radiator at the top of the case for some serious cooling. 

Inside BackSide


There is ample room to mount extra fans, and very long graphics cards. In fact, Rosewill has included a card support at the bottom-front of the motherboard area that can be used to support long and heavy graphics cards. This is a nice touch. I didn't have any cards in my systems that required this, but if you are using a GTX 980, you'll be glad for this extra feature. 

As you can see above, the offside of the case holds your hard drive mounting opportunities. There is space for three 2.5-inch drives as well as a pair of 3.5-inch drives at the bottom front. The 3.5-inch drives mount without tools, but you'll need a screwdriver to secure your favorite (or surplus) 2.5-inch drives. This layout is not as easily accessible as traditional cases, but it offers much better cable management and a clean build.

CPU Backplate Hole Card Support  & Fans


The CPU backplate hole is very large and will easily allow you to mount aftermarket coolers without removing the motherboard. Back in the early days of large coolers, this was one of the major complaints of motherboards. A hole for removing and mounting CPU backplates is now pretty standard equipment. The GPU support is made of plastic, but mounts quite securely to the main motherboard tray and should do it's job without issues.


The fan hub accommodates up to five fans and can be controlled with the slider at the top-front of the case. The front fans are plugged into it, and if you decide to add another couple of fans to the top of your system, you could easily plug them into this hub as well. The position of the hub allows for easy addition and accessibility for front and top fans.

Specifications & Bundle:

The following specifications have been pulled from the Rosewill product page for the Cullinan and have been posted here for your convenience. Please make sure to check out the complete information at Rosewill's site.



The bundle is not that robust, but does include everything you need to get a system built, cables managed and it up and running. There are more than enough screws, standoffs and cable ties to get you going as well as a few extra side panel thumb screws in case you lose a couple. All in all, it's a solid bundle.


On the next page, we'll build a system in the Cullinan and share our thoughts about easy of build as we continue on the review.

Building in the Cullinan:

The layout of the Cullinan is very good overall and I really like building inside a case that doesn't have any traditional HDD racks or optical drive bays. This makes it much easier - and when you combine the fact that the 3.5-inch HDD trays are tool-less, installation goes very quickly. While the racks are plastic, as you can see below, they are quite sturdy and lock into place on the drive securely. Once the drive is installed, they slide into the case in front of the PSU on the opposite side that we normally see. This is good as it keeps all the cables and even the drives from being visible in the main window.

There are three mounting trays located on the back of the motherboard tray that allow you to install your favorite SSD or other 2.5-inch drive. These are secured to the case with a single thumbscrew and some clever slots, but the drive requires a screwdriver to install onto the little tray. Once that is done, you can slide them back on the case, secure them and you're good to go. I only had a single drive available, but there is room for more. Pictured below is the SSD as well as a pair of 3.5-inch drive in the lower left - in front of the PSU.

Drives Installed


Once drives are installed and cables ran, we threw a quick system together to see how it all shapes up. All of the installation is very easy and our M-ATX board looks tiny in this giant cavern of a case.

Now that we have some hardware inside, we'll fire it up on the next page and show you just how amazing the tempered glass is.


Final Thoughts:

Well time, life and health prevented me from building a killer system inside the Cullinan, I still got enough of an impression when building a smaller system to share my thoughts. As you can see below, the case is gorgeous and the lights are quite muted through the tempered glass.

One thing that may be the biggest turn-off for some consumers is the lack of optical drive support - outside of an external USB unit - and nobody wants to plug a bunch of extra peripherals into their system. My reality is that I haven't used an optical drive for - quite literally - years. I can't remember the last time I used one, and even in my Thinkpad T540p, I have pulled the optical drive and replaced it with an extra hard drive. Rosewill could have cut the glass to allow for a single optical drive, but that would have weakened the front of the case and completely ruined the high-gloss, high class look of the Cullinan.

Working inside the Cullinan was roomy and even if installing mutliple liquid cooling loops and extra long graphics cards, there will be room. The bottom-mounted PSU and the cover for it, along with the rubber grommets, cable ties and other options, help you route your cables and make the overall build extremely clean - inside and out. Speaking of clean, the magnetic fan filters on the top and front are fantastic and will help you keep your system spotless with little effort. There is also a removeable filter at the bottom that slides out and is easy to clean. 

With the tinted tempered glass side panel, even bright fans emit a very tolerable glow that is very attractive. Of course this is personal preference, but I'm a huge fan of the muted glow produced by the Cullinan.

Even the front fans are very manageable when it comes to brightness and help to set this case off - whether it's in broad daylight, or in full dark.

At the end of the day, I have to recommend the Cullinan case to everyone who wants a high performance, high quality case and doesn't plan to move it around a bunch. The case appears to be tough enough for sure, but the weight and fragile nature of glass doesn't lend itself to a LAN rig. Still, it looks amazing and performs equally fantastic.




  • Looks fantastic

While I have listed a few "Cons" to be fair, none of these really affect me - or most end users. It is worth mentioning though that this is not a storage beast. Instead, it's a very capable beauty.
