OverviewCustomer ReviewSpecificationsProduct Tour
The Cosmos 1000 from Cooler Master has an acoustical performance that reminds you of the quiet of space. Extreme sound suppression was a primary focus of the design. All four of the fans are 120mm to move the most air with the least noise. The two fans on the top blow air out through a louvered duct and the intake fan is on the bottoms and pulls air up through a filter. The side panels are covered in a sound deadening material.

But it isn't just about keeping things cool, convenience also played an important role in the design process. The five external 5.25" bays have a one button locking system to secure the drives in place. Six hard drives can be installed in individual cages with sound deadening grommets. The cages and expansion slot screws are all thumb screws so you don’t need to worry about finding a screwdriver, though one is included.

At the top of the case is the control and connection panel with the power and reset buttons, plus the status LEDs. They've also included a FireWire port, eSATA port and audio jacks. Four USB ports let you connect your peripherals without having to reach around the back of your case.

Cooler Master Cismos 1000 RC-1000

white Reviewed By: billmail1 on 9/7/2007
Rating + 5
Tech Level Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: I received this case about three weeks ago (thanks Newegg) and just completed building my gaming PC. Having built numerous custom PC's in the past I have to say that this case is the best-looking and well-designed case I've ever seen. The interior of the case is a pleasure to work in. Plenty of working space and no confined areas. Even the cable management areas in this case work great. The location and use of all items (side panels, drive bays, locations of the 4 fans,) is perfect. All fans operating at high speed are almost inaudible. Even my wife took a second look at this case when it arrived and commented that it was a beauty and, believe me, she could care less about computers. Cooler Master spent a lot of time in designing this case to be user-friendly and it definitely shows. The craftsmanship is first rate, sound level of all fans is extremely low and air flow couldn't be better. You really need to see this case to appreciate its beauty, build-quality and innovative features.
Cons: There are some sharp edges in this case particulary in the hard drive bay areas. I have a few small cuts on my hands because of these but I've seen and used cases that should have a box of bandaids included in the accessory kits. Just be careful in the HD drive area.
Other Thoughts: Best looking case I've ever seen. Best design both inside and outside. Ergonomically perfect. Extremely easy to use. No fancy side windows to ruin its sleek profile and smooth finish. Other than some sharp edges inside the HD bay areas I am thoroughly enjoying the looks and performance of this case. If you really want to showcase you PC after it's built then this is the one to get.

The A-10 Warthog of Cases!

white Reviewed By: Cloud Dancer on 11/16/2007

Tech Level Tech Level: high - Ownership: 1 week to 1 month
Pros: The hard-cores got together on this project! Almost perfect. Holds (6) 3.5 inch Hard Drives in a slide out, high quality tool-less rack-type configuration. (reminds me of the avionics racks on hi-performance jets). Holds (5) 5.25" drives that secure with a springloaded push button lock. Any drive, except the (3.25"floppy) can be changed out in less than 2 minutes and that includes the time to remove the case sides! Mounting the floppy is a little tricky, but involves carefully removing the pre-mounted racks from one of the 5.25" bays, but it can be done. And yes, contrary to what has been written, you can mount one of the (4) included 120mm fans (the one in the shroud) above the hard drive racks to draw cool outside air in from the bottom of the case. Case includes 4 fans (Mountings available for 6) and works by drawing cool air in from the bottom through dust screens and venting it out the top and rear of the case. Case is roomy; has 4 USB, 1 E-SATA and more on top panel.
Cons: Better be mechanically savvy if you plan on using this case to it's potential. The documentation is very lacking, near non-existent. Specifically, mounting (moving) the hard drive fan and mounting the floppy drive takes a while to figure out. The only other possible negative I can see is that the included 120mm fans don't move much air, but they are quiet and they are included with the case. Barely a negative as it's easy enough to upgrade fans.
Other Thoughts: This case is built like a tank, easily holds anything you ever though you might put in a computer case, and looks like some sort of high tech alien attack drone. You'll want to place it where guests will see it and wish they had one. Serious Builders Only!

well insulated for noise, and is

Tech Level Tech Level: somewhat high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Big, easy to use front 3.5 bays, looks good?
Cons: Almost everything! I bought this case to move my rig from an Antec 1200, which was good, but too small to navigate through. The Cosmos is big, but that's as far as the pros go. The major cons:

1. Airflow - awful airflow, period. Only one small fan on the back and none on the front.

2. Desing - first, installing a video card is a real hustle due to an edge the designers have created over the videocard holders on the back of the case. Placing the screw to hold a video card is almost impossible. Also, I have x58 3-sli mobo and it's impossible to place a third video card as the case slots don't match the card DVI ports. If you really want to do it - grab some tools because cutting will be required.

3. The HDD bays are NOT TOOLLESS! You still need a screwdriver for the 4 screws which hold the HDD to the bay. So adding a new hard drive still requires srewing 4 screws.

See other thoughts
Other Thoughts: 4. The 2.5 floppy drive bay is useless. I bought a 2.5" Express Card to place there and there is absolutelly no access to it to mount the card reader.

Overall one of the worst purchases I've ever made. Look for another case and you'll be happier.

Trade-offs.

Tech Level Tech Level: somewhat high - Ownership: 1 month to 1 year
Pros: Spacious, easy to work in, extremely easy to organize, wonderful hdd bays, lots of exhaust options, soundproofing, slides easily on carpet, nice front port/bay access, nice little 'tray' on top.
Cons: Huge, heavy, no 2.5in adapter for a ssd, and two aftermarket adapters needed modding to fit.
Other Thoughts: This is the trade-off: you get a huge, spacious, well-managed, quiet case; but it's as heavy as a small fridge. I don't move my box, so I'm happy. If you do, look elsewhere or get a gym membership.

The absence of a 2.5 in bay adapter was a bummer, but not the end of the world. The screws on the back expansion slots can be fiddly, but that's nothing new. Overall, I am very happy with this case. It's feels very well thought through and deliberate.

Great Case, Could Be Better

Tech Level Tech Level: high - Ownership: 1 day to 1 week
This user purchased this item from Newegg
Pros: Very good build quality, probably the best i've owned. Excellent sleek looks, very sturdy, this case will outlive you. Lots of room to work with on this case, room for watercooling everywhere, and extra fans.
Cons: I spent about 30-40 hours researching cases for my next build. I decided on this one because of the size and build quality. Cons are it needs more fans. I bought withthe intention of cutting in 2 extra intake fans into the front of the case by the HD bays, and this is a MUST for proper air cooling. Not really a con as i knew this before i bought it and saw that it has the room and ability to have me do this, but the HD cooling could have been better thought out.
Other Thoughts: I am only giving 4 stars because i believe CoolerMaster should have put the 1 or 2 front fans in stock. Its nice that the case has the room to have this done so people like me can do it, but for a $200 case it should be included. Overall you cannot beat this case for modding as well as build quality, i would buy this again for sure.
