    If i may perform a quick thread hijack... :)

    A Peltier generates both hot and cold, or more accuratly it creates a temerature different between 2 surfaces. This is done (in laymans terms) by passing a current between 2 different metals in a circuit.

    Inside the peltier itself are 2 different metals which are interspersed and have 2 wires leading from them. If a current is passed through the wires, and hence the metals, a temperature difference is created between the 2 sides if many degrees. One side is extremely cold, somtimes below 0C if the external condistions are right. The other side however will usually reach over 100C, and leads to the peltier sometime sbeing described as a 'heat pump' as it shifts warmth from one side to the other. Depending on which way the current flows depends on which side is hot, and which is cold.

    Most mini fridges use around a 60W Peltier (usually) and can easily form ice inside above the peltier (interestingly, this is how some mini fridges can also warm things, but reversing the current through the peltier). However these can be used to overclock systems much further than a normal system if a more powerful peltier is employed (eg 220+W for maximum OCing). The cold side of the processor is placed on to the cpu and the hot side to the heatsink. This cools the CPU, the heat is then removed through heatsink, although for cpu OCing a WC system would be needed due to the huge amount of heat given off form the peltier. For cooling a can tho 60W and air cooling is fine. (i once built a mini fridge to go inside a case (see project Plain Lazy) but it failed, theory was sound tho :))

    Im sure theres a peltier FAQ somewhere on bit-tech which goes into this further, but thats the basic idea :)

    I'll stop hi-jacking the thread now even if it was almost on topic :)

    Nice! but I think you need to look ahead a bit more and think of what you are actually gonna do, or you'll end up with a bunch of mistakes you can't correct!

    Keep up the good work, and I look forwards to seeing the finished case! You have enough room in it, why not put an LDC screen on the front?

    I've noticed I should plan a bit more before doing stuff.. It's just boring and I'm not good in planning things..

    And I won't put since I have no any... So far this has been zero-euro-mod so I won't neither buy one. BTW it's lcd, not ldc. ;)

    Yes oh yes, this project has once again moved forward. I found solution how sidepanel can be removed with connectorplate on. :) This is REALLY good thing! Maybe pics still today.

    Finally an update.

    So here's what I've done and what has been my worst problem... Allso you can see how I temporary solved it.

    I decided to cut frontpanel to two pieces. Lower one will be fixed to it's position and only upper one will act as door.

    My lovely saw <3
    [​IMG]

    And here it's cutted.

    [​IMG]

    About 5sec after cutting I noticed my terrible mistake :wallbash: I should've cutten 5mm lower, so there wouldn't have been this problem :waah:

    And if someone didn't get it the problem is that I can't put sidewalls in places if I don't do something to that spot. In this case walls slide to front instead of normal back... And I didn't remember that :(

    [​IMG]

    Here's another pic with door closed.

    [​IMG]

    I'm still not sure what I'll do to it. That hole isn't large but clearly visible, so I don't like it at all. It allso reminds me how stupid I were :rolleyes:

    I've been thinking if I should do all new lowerpart, which would somehow hide whole mistake.. I don't know yet what kind it should be, but I'll keep thinking.

    And oh I have only killed one cuttingdisk from dremel so far :dremel: It must be my personal record :D

    I came out with idea once again. I'll cut lower part to two pieces and then glue lower of them back to door. so err..

    ->

    There'll be like 4cm of space under whole door-thing

    ->

    And that 4cm is where I'm gonna build custom-made-plexi-switchpanel. So door looks like original, it's just 4cm too short.

    How does this sound?

    I spent 15 minutes planning electrical system and I think there'll be 7 switches and 6 connectors in frontpanel. Switches will be behind door but connectors won't.

    Switches:
    power on/off
    PSU2 on/off
    peltier on/off
    fan1 5/12V
    fan2 5/12V
    lights on/off (there'll maybe be more switches somewhere else (2 coldcathodes and leds)
    headphoneamplifier on/off

    Connectors:
    Two USB2
    four RCAs (mic + headphone R+L + black sheep ;) )

    it isn´t smart with a peliter on\off buttom. it needs to always stay on or else you f*** up your comp.

    I would just take a small piece of plexi or something and put it in that gap then smooth it out with bondo.
