    The Cool Cube [small project - finished!]

    The idea of this case comes from wanting to build a case just out of fans.

    [​IMG][​IMG]
    Basic sketch of what it will look like. Sorry about the shoddynes but it would take me ages to do that in a cad program.

    A total of 18 80mm fans (none at the bottom and 2 missing from the back allowing for the mb backplate). The front 4 blowing in, put not sure about the others atm, tho will be half blowing, in half blowing out.

    The total width will be 225mm, with 175mm internal. Alowing for a via epia m with is 170mm. 15mm alluminium C channel will be used (depends whats available tho) as spacers between the fans to give it that extra width.

    The base will be aprox 25mm thickness of mdf painted black to look like the 4 missing fans. A slimline (12mm) ddvrom drive will be stealthed behind a length of C channel. Was wanting to buy a slot load ($120US), but managed to pick up the tray load of the forums for $50.

    Alluminium diamonds/triangles will be holding it all together, giving it a metal feel. And i'm thinking blue neons inside.

    I'm hoping for the edges to be curved alluminium sheet, but I haven't got the tools to do that. So i'm thinking maybe curved plastic sprayed silver (will look shit tho) or trying to find 50mm diameter alluminium tubing which i could then quarter. Thats basically whats holding me up atm.

    So what do you guys think? :)


    EDIT: finally finished, click here to be taken to the final photos

    however, that is a unique idea, and i am very curious to how it will turn out

    Good Luck !

    Imagine sticking your fingers into that...
    OUCH...

    nice idea tho...
    maybe some particitions inside to direct air flow..

    i couldn't afford 18 fancy fans :(

    the fans i'm using are
    Panaflo FBM-08A12M 12V 0.16A 80mm 29dB, 36.6cfm,

    bought 20 from ebay for $37.50 inc post

    little bit of an update:

    went to bunnings and all they had was 12mm C channel, hence i've only got 1mm on either side of the mb and fans.

    aslo bought 0.6mm aluminium sheet which will be rolled to give the curved edges.

    i've started building one side, and i've decieded that an octagon in the center looks better.

    [​IMG]

    EDIT: finished off 2 more sides and can show the basic shape.
    [​IMG]

    the two other sides are abit more complicated, being the dvd drive and the mb connection panel.

    will look better once all the other triangles are added in.

    theres been abit more progress...

    The 25mm MDF for the base was cut to size and then spray painted black (nothing really special)

    [​IMG]

    I hacked up an old atx desktop case the get the motherboard tray. 2 shots below show it attached and then the actual epia board sitting on it.

    [​IMG]

    [​IMG]

    The octagonal shaped alluminium thats going to be on all the edges was easily added to the base.
    The good thing about 0.5mm sheets is that it can just be cut with scissors.

    Finally 2 faces where completely finished, which now gives a better idea of the finished look.

    [​IMG]

    MMmm, shiny.



    The rest is quite straight forward, just alot of screws and cutting out shapes.

    Wow, that looks way better than I'd imagined it ever could. Way to stick it to all the Epia passive cooled guys out there. (Myself included)

    It will be an easy to upgrade to the dual Opteron Mini-ITX that's coming out too.

    thanks for the feedback guys.


    i just thought i would calculate some theretical numbers.

    each fan produces a stated 29dB which is equivalent to voice/soft wisper. tho because i've been handeling them quite abit, i'm sure its higher.

    hence abit of googling for equations gives the following for 18 identical fans (i think):
    total sound level = sound level of one + 10log(number of sources)
    = 29 + 12.5 = 42dB
    which is only equivalent to a suburban home/office


    also calculating the power requirement of a single fan:
    power = voltage x current
    = 12 x 0.16 = 1.92 W

    hence for 18 fans total would be 35w
    which is relatively nothing for the 200w atx powersupply i'm using (below)

    finally abit more of an update...

    Please tell me you'll be using a PWM controller and not a rheobus :p

    looks good.

    just another little update...

    the initial stages of adding the dvdrom drive to it.

    [​IMG]

    [​IMG]

    This will probably be one of the harder parts of the project. The tray will eventually be stealthed by alluminium to look like the other faces. By coincidence the eject button is situated where a screw should be, so i will be using a screw head as the button.

    I haven't thought about any of the electrics yet, just trying to get the shape together.

    Just a suggestion but i think that putting a PSU inside would be too difficult, what i think you should do is get something similar to this, it has DC/DC power supply and a external powerbrick transformer yet one of these only supplies enough to run a mini-itx mobo im not sure it would power all those fans, yet you could look into the idea :)

    Has anyone thought about the fact that all of those fans will create a bad air flow.
    Fans are based on the wind tunnal affect, air in one side and out the other. But by adding all of those fans you are simply creating a stale mat where all of the fans go at once and they end up countering each other. Thats not to say all of them will be wasted but a lot will.
