Pre-Programmed Modes

Maximize the Cooling Options

Each Cullinan MX PC case supports up to six 120mm fans (three in the front, two on the top and one at the rear). It also houses three additional 80mm-fan installation spots on the PSU shroud. With clearance to install a 360mm liquid-cooling radiator at the front and a 280mm liquid-cooling radiator on top, the Cullinan MX's cooling potential is limited only by your imagination.

Each product has been made with premium materials that provide an elegant appearance, as well as smooth and quiet operation. Plus, the tempered glass panels on the side and front display the key components inside—with both subtlety and style.

Pretty Good 9/22/2020 12:32:19 PM

Pros: -Good amount of space to work in(for me anyways)
-Good air flow
-Solid Design
-Looks Nice
-Cables were managed already for the fans and front ports

Cons: -Wish it came with velcro ties but that’s just me
-Had troubles placing in the motherboard because the I/O port of the motherboard wouldn’t really fit into to opening of the case, so I had to push it in with some force and put screws in to hold it to put the other screws in. Could be just my motherboard but yea.

Overall Review: Overall, great for my needs and looks great

Not a very good case. 9/9/2020 1:09:19 AM

Pros: Plenty of room and places to dress in cabling
Decent cooling
Room for water cooler

Cons: The screws and rubber inserts for the glass sides barely stay in and strip easily. I found that 3 of the screws had already been cross threaded and the rubber inserts had been smashed in for so long that they were deformed.

The case from day one has some loose part in it somewhere that "hums" when the GPU fans start to spin up. This was on both the 1660 Super and the 2080ti. I have taken the entire PC and case apart to find where this loose part is and still have not found it. I am thinking it is with the glass. If I lay the case on its side the hum goes away.

The RGB on a few of the fans started doing their own thing after about a week. I think this is a bad controller. While the fans work, the RGB randomly freezes on one section of a fan in a random color....

Overall Review: I don't recommend this case due to the fact it is less than a year old and already ordering a new case because of the problems it has had.

Cheap materials = cheap operation.

Very nice 9/4/2020 8:49:34 AM

Pros: Very sleek small form but plenty of room.

Cons: Needs a filter over front fans. I purchased a magnetic one separately.

Overall Review: If you are looking for a smaller form but supports an atx motherboard this is a great option.
