COOLER MASTER COSMOS 1000 RC-1000-KSN1-GP Black/ Silver Steel ATX Full Tower Computer Case

  • Steel ATX Full Tower

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.

  • newegg Supreme Expandability with 11 Drive Bays Boasting five external 5.25" drive bays, and six internal 3.5" drive bays, the Cooler Master Cosmos 1000 provides supreme expandability.
  • newegg Ultra-quiet Operation Featuring a sound barrier design, the Cooler Master Cosmos 1000 applies soundproofing materials inside the chassis to minimize component vibration and block system noise for silent operation.
  • newegg Maximum Cooling The Cooler Master Cosmos 1000 is equipped with four 120mm fans (one at the rear, two on the top, and one at the bottom), a VGA air duct and a dedicated 120mm fan mount for HDD, providing maximum cooling for your computer system.
  • newegg Tool Free Installation The Cooler Master Cosmos 1000 features finger pressing buttons for easy installation or upgrade of the 5.25” devices.
  • newegg Convenient Top I/O Panel The Cooler Master Cosmos 1000 features a convenient top I/O panel for easy access to four USB 2.0 ports, one IEEE 1394a port, one eSATA port and two audio ports.

5 out of 5 eggsPerfect full tower case

Pros: Very large, made of high quality material, power and reset buttons feel premium-made, has lots of space for expansion for even the biggest of graphics cards. Has a multitude of front panel connections which include four USB 2.0 ports, an eSATA port, FireWire, HD audio and mic. Side panels are pop on-off, there are no screws it just has a latch mechanism which is easy to put on and off. Even after seven years it still looks to be well worth its $199.99 asking price.

Cons: It is very heavy but I guess that is not really much of a con as it is, per say a statement of its great craftsmanship.

Other Thoughts: This is quite possibly the greatest case of 2007-2008 era.

5 out of 5 eggsStill great

Pros: I'm not really sure why I am leaving this review as the case is no longer available, but I figured I would leave my input anyway. I bought this case in 2009! 5 years ago... I use it for my work PC and even to this day I still get comments from clients amazed at it's size and looks. When this thing is all closed up you cannot even tell that the computer is on it's so quiet.
I noticed a reviewer below mentioning a few things such as the front panel not latching and the front ports prone to failure. He never said his failed and I would like to point out that after 5 years of moving this case from work to home and back to work and even to new buildings nothing has ever went wrong with it. I was concerned at first about the metal bars used for feet and handles as I thought they were slightly loose, but even after all this time they stay point and perform great. All of my front ports work great and the front panel latches closed via the magnet very well. The previous reviewer might want to make sure his case is level.

I was in the process of looking for a new case for a new high end pc build to replace my 5 year old pc still sporting an old school unavailble i7 processor and I cannot find a case like this one. I was hoping cooler master had a new and improved version but this is still a unique case and I think I might still use it for my new build.

Cons: To me this isn't a con and anyone reading descriptions will know better, but this case is quite heavy even empty. I didn't bother to go back and look at it's weight, but with a pc parts in it the tower has quite a bit of weight for being aluminum. To me that just shows it's craftsmanship :)

Other Thoughts: If you are still reading this review and you can find one of these cases used don't hesitate to pick one up. They seem to hold up very well to age and abuse so you can't go wrong.

5 out of 5 eggsMy first and best case ever!

Pros: This case is my first case in 2007, but sold it after modding. I've own two of them and really miss it. I come back check see if they still sell it but not :( I would love to buy it again!

Cons: none

3 out of 5 eggs

Pros: I want to love this case.
Multiple Hard drive bays, Great Cooling, Spacious, Quiet, More than enough tools to get everything set up.

Cons: However,
The doors on the case never lock, the lock mechanism is faulty plastic, the front ports are finicky and prone to malfunction.

Other Thoughts: Can't stress the risk that comes with this case. It's a big investment to make on something that you can't guarantee will work.

4 out of 5 eggsBest case I have ever had, but HUGE!

Pros: Absolutely stunning looking case. Very sleek and clean. It is huge, but it does give you plenty of room to put whatever you want in there. It is also pretty heavy, but very well built aside from the front panel.....more on that in the cons. The handles on top make moving the case a snap (just make sure you lift with your legs). Brushed aluminum finish on the side panels is a nice touch.

Cons: Just a couple and they are pretty minor.

1. The power supply is located on the bottom, which isn't a big deal, but unplugging it if it is back up against a wall kind of a pain.

2. The front panel kind of 'came loose' after a few months. It is still usable, but when you plug in a USB cable it kind of 'gives' a bit. There is no access to this panel without dismantling the case, which I have no desire of doing. So this loses 1 egg for me.

Other Thoughts: This is a big 'ol case, I knew it was big going it, but was pretty blown away when I actually received it. It is huge. Other than the little niggles in the cons, I am very happy with the purchase. I would buy a Cooler Master case again.

4 out of 5 eggsI love it!

Pros: - Lots of room
- Good air flow
- Quiet
- Solid

Cons: I took away one egg for the door latch but it is fine if you apply grey matter.
In order to make the latch close securely you have to remove a little foam where the door contacts the latch bar and press hard just over the bar to make it snap all the way closed, you can tell when the release lever is all the way down.

Other Thoughts: This case will last the rest of my life if I don't abuse it.

5 out of 5 eggsGreat case

Pros: Nice roomy case.. good airflow if you do the following: Replace all three fans with Scythe S-FLEX SFF21E 120mm fans. If you are doing overclocking, but don't know a ton about water cooling, then pickup the new Eco from coolit. Install the fan on it to pull air into the case instead of it's default 'pull out' Your top fans will vent out the hot air. Before I did this I was running 40 C on Idle, and pushing 72C on full load. Now it's running under 30C Idle, won't go over 62C under a full Load. (Overclock to 3.82Ghz... ram is oc'd to 1603 Mhz.) I've got a GTX 285 and it runs nice and cool as well. (All purchased at newegg.) Before I did those mods (And I built this about 18 months ago..) I thought the case was decent but wouldn't buy another or recommend it.

Cons: Airflow out of the box box is great if you are not overclocking, and playing solitaire with a built in Graphics chip *grin*

Other Thoughts: If you do want to overclock, then it can be a great case, with a few cheap modifications.

The case is beautiful, and runs nice and quiet.

5 out of 5 eggsGreat case only lacks USB 3.0

Pros: Classy style, handles make it easy to move, good air flow, a ton of room inside makes it ideal for users with big hands, lots of ports in front, plenty of room to upgrade.

Cons: Only con I can think of: lacks USB 3.0 ports.

5 out of 5 eggsFantastic case that is a timeless design

Pros: This case has been somewhat of a dream machine desire since I first saw this in a magazine quite a few years back, it's simply beautiful and the build quality is top notch. The brushed aluminum side panels and front door look amazing and the easy open latches at the back make accessing your system super easy. The case is heavy but the bars on top and bottom make this easy to handle. There's pleanty of room inside, and it's great for an EATX (which I have). The tool-less 5.25" bays are also excellent, but I always worry they won't hold after long term use. You'll also never have to worry about whether or not you'll buy a video card that won't fit, they'll all fit no matter what. I love the inside so much I just had to buy a replacement side door with a window to show it off.

Cons: This case is made with top notch materials, which make it sturdy and beautiful, but it comes with a cost: weight. 50lbs without any parts in it is just excessive for some, for me not an issue though.

For an ATX motherboard this case just feels way too big. at least 4" of space between the motherboard and drive bays, and that can be an issue for some PSU cables.


*this is a note on shipping, not the product*
I had to have Newegg file two claims with UPS because my first and second shipment had a delivery exception of "MERCHANDISE IS MISSING. ALL MERCHANDISE MISSING, EMPTY CARTON WAS DISCARDED." which to me means it was stolen off the truck by the driver or it was completely manhandled. The packaging was hard to tear open so i doubt the packaging tore, but Newegg ships these boxes by just slapping a label on the side of the retail packaging. I can easily see someone thinking this box was a completely built system (Fancy pictures, 50lb weight, no mention of it being just a case)

Other Thoughts: Newegg was great on replacing the "missing" shipments, but it did delay me two weeks in building my system. I also plan on tearing this case apart and having it powder coated, which will be another delay on my part. I just want to build this system and see it running, and I know when it's done it will be beautiful. This by all means is a beautiful case but it's a shame that a delivery company can "lose" a 50lb MASSIVE box twice.

1 out of 5 eggsIt's in the trash

Pros: looks nice
large enough for all my equipment
cool hdd bays would be 10x cooler if they were hot swappable.
sound dampening

Cons: door latches suck, doors kept falling down finally had to throw them out leaving an ugly open aired case.
then the front usb's stopped working, front audio soon to follow, power button would only reset computer after about 6 months, ended up being a short in the wires. power light failed, airflow is heavily impeded. filter tray on the bottom broke.

Other Thoughts: threw this thing in the dumpster and bought the ABS Black Pearl a few months back, while the ABS Black Pearl doesn't have good wire management it's ventilation is good and best of all the doors don't fall down. while i had a bad experience with the cosmos 1000 i have had good experience with the company in the past and will browse there selection when building my wife's new rig.
