Got the Coolermaster Cosmos on Wednesday. As expected it was a bit of a beast - especially in its packaging. Carrying it up 2 flights of stairs was 'fun'.

It has 4 large handles; 2 top, 2 bottom, which make transporting the case a lot easier than it would have been otherwise. As an added bonus they don't dig into my carpet as regular case feet would and enable the case to be maneuvered quite easily.

There's tons of space to work with inside and a very good clearing around the motherboard meaning I can pretty much use whatever air cooler I want.

I'm going to use this case as an all-in-one work/gaming/storage machine. For the gaming side of things I'm not going to be going SLI so just about any case would be fine. However I do want to install 8 hard drives but this case only has space for 6. I knew this before I purchased but I thought I'd just use up 2 of the optical drive bays for hard drives instead...

.... and this is where the problems start.

The cosmos has this 'unique' push-button locking mechanism which works GREAT for optical drives. There are however some incredibly bad design flaws which go with this. First of all, you cannot screw anything in easily as the push-button locking mechanisms are a 'tad awkward' to remove and on the opposite end there's no access to the screw holes as a big metal plate covers it all.

In addition to this the vent for the hard drive area is positioned above, leading straight into the bottom 5.25" drive bay, which basically means you can't put anything there unless you want your hard drives to suffocate. So where did the genius's at Coolermaster decide to position the only 5.25" > 3.5" adapter? Yep, right there. It needs to be screwed in, and that's the only slot that provides access to the mounting holes on both sides of the case.

Don't get me wrong though - I love this case. Its just a shame its looking like I'm going to have to spend a fair bit on purchasing up to 3 full-size 5.25" > 3.5" bay converters and some extra cooling.

Speaking of cooling, I bought the Scythe KAMA-BAY Black System Cooler which looks great with this case but of course there's no way to install the bugger.

For those of you who like to install ANYTHING other than an optical drive into your 5.25" drive bays; this isn't the case for you. Even if you manage to install what you want to - the door is very unlikely to shut if there are any protruding bits such as fan controller knobs.
 
I was/am still considering the Cosmos, it fits 80% of my needs and has the looks and silence factor which I require but.....

As your said bad design flaws, the Cosmos has no Direct Hdd cooling and ive noticed even with 3 large 500giggers running 24/7 things can get hot!

Even the GTX.... theres no real decent VGA cooling that VGA duct doesnt do much according to reviews. And a hot GTX/system isnt gonna go too well.

They could have added a 120mm side fan but nope. A few reviews do say one fan at the bottom intaking cool air and 2 of em outputting air just doesnt work...

It is designed for silence but I got a feeling heat will be an issue in that case so am trying to avoid it.
 
With regards to why there's 3 exhausts and only 1 intake; its to do with creating negative air pressure.

The idea is it causes air to be drawn in via the vents, specifically the one beneath the hard drive area, which draws cool air in, up through/between the hard drives and out the top. The VGA duct is also meant to work in a similar way but due to its orientation I can't see it actually doing a lot.

Any pics ?
Coolermaster has a micro-site for the Cosmos which has quite a few views on the case.

Also if you google for "coolermaster cosmos review" you'll find a link to a review fairly high up in the results that has tons of pics.

If you want me to take a pic of a particular part of the case let me know.

Edit: Forgot to mention, there's a space (sort of) for a fan above the hard drive bays. which should help cool them down a lot. You'll need a special mounting kit though (which will use up 2 x 5.25" drive bays) or alternatively you can just selotape a fan on its own in that position.

Yeah I hear the negative air pressure thing a lot in reviews some say its good some say its bad.....undecided really.

Yeah noticed those air vent holes near the hdd caddies I thought they had made holes for a 120mm fan there/

Still its a lovely tempting case...
 
It goes ontop. You screw the fan into a shroud (purchased seperately - but not available atm as far as I can tell) then clip the shroud into place.

It won't actively cool the hard drives like a cpu fan does the heatsink. Instead it just helps air come up through the vent at the base of the case; cooling the air around the hard drive enclosures.
 
yeah thought so... still I think with a bit of modding it can be modded with some decent cooling.

Wish they would add some side panels on both sides and add some side 120mm case fans that would do the trick ;)
 
A lot of modding I'd say. In fact you'd have to completely rip out the hard drive section and put new standard brackets in. The metal casing of the hard drive 'caddies' don't make contact with the hard drives. This means they are not going to act as a heatsink as you would've thought from the photos. The reason for this is because the hard drives are mounted through these rubber rings, which are glued onto the 'caddy' as carefully as McDonald's employees make sure the cheese goes in the middle. After mounting, there is about a 1mm gap between the sides of the hard drive and the sides of the caddy. I'll take a photo of this later.
 
Thx I think your refering to the hdd grommets ?

There those noise dampeners, perhaps its possible to leave a few hdd caddies out and simply mod a 120mm fan blowing across the hdd units ;)
 
I read on the coolermaster forums some guy removed some of the empty caddies and it made sod all difference to hard drive temps and I can believe that.

Where would you position the fan? If you put it at the front like in most cases, it will just hit a 'brick wall' due to the orientation of the caddies so won't blow over any of the hard disks.
 
My dremel arrived today!



Don't know if I was more excited about this arriving or the Cosmos!

What I've got in mind so far:
  • Cut 2 vertical strips out about 15mm wide on the right hand side of the 5.25" drive bays to provide access to the mounting holes on that side.
  • Cut out the vents at the top of the case where the 2 fans are mounted.
Any other suggestions for mods to the Cosmos?
 
Id be scared to even take a pin towards a £150 case lol

In fact I cried when I scratched my Eclipse 62 ;)

But yeah id focus on trying to get hdd cooling going or even VGA duct ? or a 120mm fan for the side case to vent mobo+VGA heat out.
 
Watching the demonstration video that came with it and watching the sparks fly when cutting metal has me a bit worried now (especially the bit where the cutting blade thing flew off).

I think there are enough fans taking hot air out but an intake right over the graphics card might be a good idea.

Have given it plenty thought and still not sure how I can mod a fan to cool the hard drive area in a useful manner. Its those damn caddies which are causing the problem. Even pondering cutting the entire section out and installing a Lian Li hard drive bay rack with a blowhole in the front of the case. Probably a little too ambitious....
