hello guys

first of all I'm sorry for my english..

..because I can't find case which meets my requirements, I decided to design my own case

Here is what I got so far

original size
http://i35.tinypic.com/2dhyxkk.png

top 120mm fan, back 3x80mm, W270xD270xH240mm

5.25" position is for Kaze Master
http://www.scythe-usa.com/product/acc/028/km01_detail.html

it's for a workstation, want it to be the smallest as possible but functional

CPU Intel i7, midrange VGA (waiting for new nvidia cards), MB msi X58M (chipset is about 65°C ), 2xHDD, no drives, no mess in cables

somewhere on the side of case will be USB ports, (maybe) handle on the top, feets on the bottom, noise reduction foam inside, considering to do the fan holes circular and remove the fans from the frame, but don't know if it increase noise (especialy two 80mm fans next to each other), what do you think?
next thing, do you think the top fan would be needed? I gave it here to do some flow around the chipset, but don't know if back fans are enough

appreciate any help or suggestions (for example better cards mounting )

Whoa!
Thats beautiful!

Looks nice. I think you'll run into some flexing and buzzing. Have another look at the top front and rear of the lower assembly to secure or strengthen the edges. In what program is that rendered?

why not put a 230mm fan in the top? Considering there isn't much in the form of intake on it... otherwise looks quite good. Only issue I see is that your expansion cards might not fit into that design- I'd say just leave the part of the back of the case that's directly over them empty, and then put it on the other part that slides onto it- that way you can slide your expansion cards in, and then putting the the top of the case back on secures them. So cut off the part I boxed in red:

and then put a flap on the other part of the case that covers that.

Edward6287: thanks, but I'm not sure if I understand what you mean by this
"Have another look at the top front and rear of the lower assembly to secure or strengthen the edges"
I want to stick that silicon seal (with groove) on the top part so it will hold case together (a little), you think that screws are not enough or metal sheet is thin?
btw. want let laser cut it out:) model is in Cinema4D, rendered by Fryrender
Spartacus: I guess intake with 120mm fan is enough, dont want it perforated too much because of dust and noise
standard expansion cards may fit, or I dont understand again
dont want to give there bigger fan because of height of case and components under it

[Spartacus]

I edited my last post with a better idea. Expansion cards would fit, but I'm not sure how you would actually get them in there with that design is what I was saying. also, 230mm fans are actually quieter then 120mm fans, and you can just use a swiffer dry sheet for a filter. Did it with my case, works great.

[rebit03]

thanks now I get it, thought I will put card in the MB and then slide it in:)
or just bend back to put card into a slot:)
I will consider to do a box of it and put bigger fan on the top:)
do you suggest intake or out take?

[Edward6287]

[rebit03]

so guys, what do you think about the fans without frames?
tried to find something like 200mm fan, but here (czech republic) isn't much to choose from , more it's all for out take
do you know any good shop sending to another countries? maybe someone from Germany?
edit: do you know where could I find fan hole dimensions for these bigger fans? (at least screw holes pitch)

[Edward6287]

See if this link helps: http://www.misco.de/

I do not know anything about the store. It is owned by the same corporation that owns TigerDirect and CompUSA. I found the link from a different discussion on the forum.

Please go back and resize your picture in the first post. It's too large to fit correctly into the forum format.

[rebit03]

thanks for the link, suppose I will make it cube and give 2x120mm intake fan to front top part

any ideas about fans without frames, anyone?

anyway, thanks for all replies, I will post progress as soon as possible

[Spartacus]

the fans without the frames should work fine. Just use a fan grill with them. In my experience, though, sometimes the vibration of the fan causes the grill to buzz- if that happens, what you want to do is take the parts of the fan grills that the screw goes through, and bend them down a bit so that the only part of the grill touching the case is the part that's screwed down. There are also silicon fan vibration dampeners that you can use in addition to that strategy- they're quite effective in my experience.

[rebit03]

ok. just a minor update

usb holes added and top fan hole removed, now kaze wont be necessary, so I will remove 5.25" position as well
first thought was to do clean design case without much preforace and when I was doin that two top holes for fans I realized that this is not what I want to do (and it was ugly too ), I think that 27 cm is not so much for 80mm fan to take air from so maybe add one or two perforace lines to front part on sides?
it will probably need some test to do..

now I like it, but I don't know if the cooling is good enough..

[rebit03]

Danthrax66: That's exactly what I don't want to do. Because then I can stay with the desing I posted here at first.
Anyway I am kinda busy so I think I can give it some time..

Thank you for comments.

[Danthrax66]

It is always better to have more intake than exhaust.

[rebit03]

ok, thank you
have to give it some time, maybe any idea will come along:)
or maybe I end up with what I post at first time..

Um 2 quick questions.
First off, I dont see anyway for you to get Power Cables up to the motherboard tray from where the PSU is sitting. At least from the way your reneder looks, the motherboard tray completely covers the PSU and HDDs.
My last question is more of a concern. I know you are looking at a Midrange card, but remember cards are getting bigger, You might run into clearence issues with the length of the card.

To be on the safe side, I would add about an inch or so of extra space on the front side of the motherboard.
