Designed with three angles of sturdy tempered glass in front and on both side panels.

Supports various gaming hardware configurations while maintaining cool system temperatures with four pre-installed 120mm blue LED case fans.

Mount an optional graphics card vertically, up to 360mm long, then show off its aesthetics with an optional riser card.


The magnetic dust filter on top of the case protectively stays in place to minimize particle buildup and is easy to remove for cleaning.

A Large magnetic dust filter in front shields case fans and maintains particle-free, constant airflow.

The removable dust filter below the PSU mount makes it easy to clean out any excess dust from the bottom of the computer case.

Improve airflow and clear away heat from the PSU-shroud basement via the built-in vents—and also with the option to add three optional 80mm fans.

Install either two HDD or SSD drives on the cage, plus an additional two SSD with the included drive slots.

Install up to two additional HDD or SSD drives on top of the PSU shroud.
Pros: + This case is gorgeous. Having been a PC builder for 20 years, I've built in everything from a $20 beige no-name box with a 300w power supply to a $300 Lian Li fully aluminum case. It's rare that a case surprises me, pleasantly or not pleasantly, and the Cullinan is a pleasant surprise. Just gorgeous. I love minimalist cases; I'm less a fan of windows and LED's and more a fan of a classy, flat, unassuming computer case. The Cullinan gives you the best of both worlds if you're like me...the glass is tinted and dark enough that it's not exactly see through, and the LED fans can be tamed (and the LED's turned off) if you run them on Low speed + The glass is very nice. I didn't know how I'd like it, and was slightly concerned on thickness and how sturdy it could be, but...it's fine. Each side panel is just under 1/4" thick (in glass) and feels as sturdy as the Cooler Master ATCS 840 I've owned before (which had very thick aluminum side panels). + The included fans are very quiet, and you're getting 4 of them! I don't have a sound meter to test actual dB ratings, but after connecting the rear exhaust fan to the built-in fan hub and running all the included Rosewill LED fans on High, they were barely audible over general room noise which is supposedly around 35 dB or so (with no other sounds, such as TV or music playing). They do move an acceptable amount of air; since they're so quiet, I can accept some loss on airflow. They'll do the job without really being noticeable, that's for sure. If you run them on Low, you're not going to hear them (or see them) at all, but I can't say I'd run them on Low while gaming or running a system on mid-to-high CPU load, but that depends on other factors too (like CPU make, overclock, and HSF). They are very bright, but due to the tint on the glass, it's subdued more than you'd think and actually looks very nice. + Speaking of which, the Cullinan had no issues keeping my OC'd i7 4790K w/Hyper 212 Evo / OC'd GTX 980 system cool. Load temps during gaming and running Intel Burn Test never went above mid-60's on CPU and GPU both. (Identical in performance to my S340, mentioned below.) + Before getting the Cullinan, my current case "flavor of the month" has been the NZXT S340. It has a window, but inside is very clean, and it's (again) a nice, unassuming PC that can house a weak little web/email system, or a 4K gaming rig. The S340 is definitely one of the better clean inside/cable management cases that I've owned, and the Cullinan for the most part steals all the positives of the S340. The cable "tunnel", hidden PSU/HD areas, easy to remove and clean fan dust filters, and plenty of cable management loops and zip tie spots all hit the nail right on the head with both the S340 and now the Cullinan. The Cullinan also has room for 1 more SSD and 1 more 3.5" HD as well, plus the built-in fan controller, so it's head and shoulders above the S340 for me now. + This bears repeating - dust filters, dust filters everywhere! EASILY REMOVABLE dust filters! Thank you!!! + Even though I'm an 'air cooled' guy, the Cullinan has forward-compatibility to run 2x 360mm radiators internally, and has the punch outs to run a loop outside of the case as well. + The cable "tunnel" does have 3 grooves for extra long graphics cards to be supported and not slant downwards so much. My EVGA GTX 980 ACX 2.0 card did not reach far enough to really take advantage of the groove, but obviously longer graphics cards will.
Cons: - The expansion card "slider" holder piece really has to be removed to install a graphics card or other expansion card easily. Luckily, it's just 1 thumbscrew, and it pivots and comes out the back of the case. You could try to wedge a card in there without taking that out, but I wouldn't recommend it. The manual even says to remove it, then install your card, screw the card down, then put the "slider" back in place for extra protection/stability. - The fans only light up on High speed, and are only blue in color. That may or may not be a 'con' to you. They do have a LOT of LED's in each fan, in a neat pattern. Most LED fans that I've had in the past only had a 4-5 LED per fan so they didn't light up as much. - Since the right panel is also the tinted glass, your cable spaghetti behind the motherboard and where your PSU/HD's are does show up a bit over there, even if you keep it nice and neat. It's not too terribly bad though. - Fully loaded, it is a bit on the heavy side (due to all the glass).
Overall Review: * Minor quibbles aside, I have absolutely no hesitation in recommending this case to anyone looking for a classy, understated case. The glass and the design is just beautiful. There is a Rosewill logo etched in white at the bottom of the front panel, but it barely shows up with the case fan LED's fully lit. * The only possible fly in the ointment is a competitor's case - the Corsair 460X RGB. Currently, the Corsair is priced more than the Rosewill, but the Rosewill is on sale and has a higher MSRP. Keep this in mind. Both cases are very nice; I don't own a 460X RGB but from what I've seen, it's very similar (internally) to the Cullinan, except it has 3 full RGB fans instead of 4 blue LED only fans, and the right side panel (behind the motherboard) is a blank steel panel instead of glass. If you wanted glass throughout, there's the Corsair 570X RGB, but that one has a bit of a higher price over both the Cullinan and the 460X RGB. I do think the Cullinan offers better internal cable management than the 460X RGB, so if a cleaner inside is more important to you than "other than blue colored" fans, well, the Cullinan is definitely a better choice. Again, I don't hesitate to recommend the Cullinan, but, compare it to the 460X RGB and see which is more preferable for you. * This is the first Rosewill case I've used; I've had many other Rosewill products in the past and have always been happy. I'm very impressed with the build quality and design of this case, and will definitely keep Rosewill cases in mind in the future if and when I'm wanting a new case (or recommending one). Very happy with the Cullinan though...a definite 'home run' of a case - absolutely beautiful, and at a pretty good price.
