COOLER MASTER COSMOS S RC-1100-KKN1-GP Black Computer Case

Posted

Pros: Looks great, incredibly well built, handles make for easy moving, lots of room for large coolers and video cards

Cons: No cutout for backing plate, needs more space behind mobo tray

I bought the Cooler Master Cosmos S as a replacement for my Thermaltake Chaser MK-I, mostly because I was looking for something a little less... chunky. In style and build quality, the Cosmos S is outstanding. The handles are sturdy, the case feels well built, the finish on the side panels is to die for, and the latches to release them are slick. It is a beautiful case.

Inside, the quick release 5.25 bays are well designed, and the 4-in-3 drive bay works well enough, though I would have preferred something like the Scout's sideways bays, for easier installation and removal. There's plenty of room inside the case for my 2 560 Ti's, and before it was water cooled, I was using a Cooler Master Hyper N520, with at least an inch to spare. There are a huge number of fan spaces, and my RS360 rad fits inside the case with fans on the bottom, allowing me to place more in the rad tray on top if I ever feel I need to go to a push/pull setup. I also wish it had a cutout for the backing plate for easy changing of coolers / water blocks, but nothing a Dremel can't fix.

While the inside of the case is very roomy, the backside behind the mobo tray isn't. I have a non-modular PSU, and with my Chaser, I had no problem cramming all the loose cabling back behind there. In this case, I have to use the space underneath the HDD cage to hide those cables, the back panel simply will not go on if I try to put them behind the tray. Also, for the 8-pin on the mobo, I can't fit the connector behind the rail that the side panel locks onto, so I cannot use the cutout above the mobo.

Most people don't take apart their cases to paint them, but here at OCN that's a real concern. This case is difficult to take apart. I broke quite a few of the tabs that keep the plastic shells on the cage. However, it was a tight fit getting them back on anyway, and I don't think they're going anywhere.

In all, the case has served me well, and it is an absolute joy to look at. It's got ample space to fit all my goodies, plenty of excellent cooling, and is very well built. If you're a case modder or a fastidious cable manager, the Cosmos S might give you some grief, but it'll look good doing it. When it's time for a new case, I'll definitely be looking at it's successor, the Cosmos II. Hopefully they've fixed the few problems the case has.

Pros: Large, Great airflow, Great cable managment

Cons: Heavy

I was looking for a case a while back that would harness what I needed to complete a watercooled crossfire machine. I began looking at several cases with both higher and lower price ranges. The main focus point of the cosmos was that it caught my eye. The design is flawless, A well build strong case that you can actually be proud to own. Instalation was a breeze! When the machine was done I was debating on I wish I had a side window, Luckily coolermast sells an aftermarket side panel for about $30. My machine was overclocked watercooled and loaded with the latest DX11 cards in 2009. I enjoyed this case and would love to do many more builds with this case. I would say of all of the cases i have owned this one is by far my favorite even 3 years later!thumb.gif

Description:

The Cooler Master Cosmos S is the latest PC chassis in the new Cosmos series of cases. Like its predecessor, it's designed for both function and style. The sleek design includes sturdy metal carrying handles at the top and bottom. There's a red-lit touch-sensitive power button at the top front for easy access. Behind it, a sliding access panel reveals four USB 2.0 ports, an IEEE 1394 port, microphone and audio output jacks and an eSATA port. A simple release lever on the back allows both side panels to pop open for easy access. These side panels have a mesh design for superior ventilation. In addition, a huge 20cm fan built into the left panel draws in cooling air while 12cm fans located at the top and rear draw air into and out of the case. Up to three fans can be mounted inside the upper front of the case for additional air intake and a total of three more 12cm fans can be mounted at the top for exhaust. Retaining holes in the rear of the case are ready to accept hoses for a liquid cooling kit and there is room for a 12cm radiator in the base and back of the case and a 3x12cm in the roof. Keep your system ice-cold without having to cut up the case! The case will support ATX and Extended ATX boards along with seven expansion cards. Seven front-accessible 5.25" drive bays and four hidden 3.5" drive bays give you plenty of configuration options.
