    put all the 1/4 copper pipes and bent it properly to have a smooth free flow of refrigerant and installed the high & low side valve connectors and after that drinking time :toast:

    Now my home made mini A/C is starting to form, I only used the one row of the evaporator coils on this build to ensure that i have enough back frost to the compressor to cool the compressor windings

    I calibrated my capillary tube length outside first to test the refrigerant control if its perfect,
    (fine tuned several times :wtf:) Now ived made a mini heat pipe for my NB heatsink, this chip runs very hot:eek: so I added some capillary pipes and soldered both ends and place another heatsink and a small fan to it:shadedshu

    I assembled my remote controlled thermostat and fan control on my mini A/C,
    damn samsung board is very hard to re activate, it had a sensor for the input frequency (60 HZ) aside from the air flow sensor and the coil sensor, DAMMIT samsung!

    but i like the polyphonic tone on this control board, its OK if its very hard to modify
    as long as its precise and has a cool tone but freakin hard to modify:cry: ived taken this circuit board from a dead 18,000 BTU split type aircon and put it on my home made mini A/C

    I installed everything and put a 5 Watt flourescent light bulb on the back on the evaporator(controlled by the remote control to turn on or off), and installed my newly bought (USED) 8800 Ultra and :eek: my 12 Volt rail is dropping:wtf:

    I installed another modified PSU just to power the 8800 Ultra, :banghead: now i cant add anymore optical drive, just one and only one:cry:

    I soldered the two 6 pin connectors directly to the PCB of the Videocard to eliminate the voltage drop on the connectors

    Im so excited on this pic that i ran it the whole day to test the stability of the mini A/C cooler without the paint and i get a cold and runny nose because it still has no front plexi glass so all the coldness is also circulating on my face:shadedshu

    I only set the temp. control to 15C/59F, it can go down up to -2C if i set it to the lowest but
    everytime i breath on the front plexi glass, it forms a cloud of mist already outside the plexi glass LOL and im afraid i might fry my motherboard or fail my HDD and im a bit tight on budget bro :( that`s why im sealing my PC in a case so that there`s no dust particles that will stick to it, I wanted to prolong the life of my Antique Artifact PC :laugh:

    Im doing this Case mod as a hobby, just to have a pass time activity, my hands get very itchy if i have no work to do, specially on weekends, my work is only 5 days so i have a free time of two days :eek: no work, i think sleeping all day on my weekends makes me sick :laugh: now its done i need to think of something again to mod before i get bored again.


    Any ideas?

    I love it! I don't know how looking through a plexiglass window would be, but the concept is indeed pretty nice. good work man, and it was nice to see the start to finish without having to wait too!

    Nice work. Just it would have worked better if the box was smaller & you had the monitor & the pc's psu on the outside.

    Pretty nifty, but if you can handle managing the compressor and stuff, why not try direct die chilling? :)

    Pretty good idea for the pare heatsink/heatpipe thing lol! At first I thought you had just taken the door off a fridge, and put a PC inside... but this is way way more effective.

    Thats a mini AC ? This thing looks huge :p
    Nice mod but is it really worth it ? The temperatures dont really look so low.

    Looks interesting, but I gotta ask, why is the monitor on the inside of the plexi glass, or the tower. I assume the tower is because moisture?

    The first pic is the start-up, turn on my PC and turn ON the split type mini A/C
    The second is after 3 hours of downloading movie trailer of the Transformers
    The third is after playing Call of Duty World @ War Game, I got killed by a suicide (BANSAI) attack :banghead:

    Those core temps are AMAZING.

    I once (years ago) asked people if I could take off the door of my mini-fridge and put it directly next to my PC case, but they said condensation would form and fry everything :(
