I am building a new rig in the next few months, and I think I want to lean towards water cooling. I have a plumbing background so set up should be very familiar to me.

►Proposal:
◘I want to use some form of water "Chiller" to keep my PC cool.
*Aquarium Chiller, Laboratory Chiller, Drinking fountain Chiller.
*Some method of reliable cooling that isn't effected on ambient temperature.

►Hardware to be used:
◘Case:I love my Wooden case, even if it isn't conducive with cooling.
◘CPU: I5 3770k or I7 4770K (currently undecided )
◘GPU: Single GTX470 4gb (possibly going sli in the late future)
◘ All other hardware has not been picked out yet

►Goals:
◘ I am going to be over-clocking, but nothing extreme. Using the purposed type of equipment may be over kill, and I realize that.
◘ I want to go about using this method for three main reasons:
1. It should allow me to use my current case by having an separate external cooling source.
2. I want to use an external cooling solution in order to move the noise of the cooling system away from the PC location(which is high up and projects in the room) and into a near by closet.
3. My room is small and stuffy, and tho I have an AC in it, it has to compete with the heat given off by the PC. I want to put the cooling system in the closet to move the heat out of the room a bit. Hopefully that will allow the AC to not work as much.

►Perimeters:
◘The PC is sitting roughly 70" above the floor.
◘The future possible location of the cooling system will be in a small closet, with a total distance of around 120"-160" from the back of the pc, requiring twice that length in water tubing.
*The cooling system may be placed on the floor or fairly high above the case remotely.
◘Depending on how I rearrange the contents of the closet I would have roughly around, enough room for 3 standard size PC cases. I can't be more exact about how much space I have to work with in.

►Budget:
◘I realize this is a bit of an exotic concept to be going with. I would like to stay under $400, even then I find that a lot of money to be spending on cooling. For now it's just a number to consider but not to be completely firm on.
◘I am a DIY guy, to save money, I will be considering options like using a used drinking fountain chilling unit with an added pump, tho i have no idea if something like that would be practical for my goals.

►What I need to know:
◘ I have read people doing things like this with good success, but I don't know if there are any details I am missing. Please point those sort of things out.
◘ I don't know what sort of products I can choose from. Please suggest options.
◘ I tend to over simplify things in my mind. I am under the current concept that after plumbing the pc case, it's just a matter of attaching it to a cooling system. I am unsure if I need much of a control system for the cooling system?

Thank you for your future help. Please ask me anything if i can make things more clear.

yes sounds good just needs a strong enough pump to give you good flow rate for that distance but your still talking an idle temperature for your cpu of 8-10c above room temperature,
I can see the pros and cons of spending money on an idea that might not work but if you decide to do it keep us up to date on how it works out

sounds an interesting idea, there is this sticky on below ambient water cooling http://www.tomshardware.co.uk/forum/275185-29-exploring-ambient-water-cooling worth a read before you start
I've been toying with an idea myself thats not too extreme, I was thinking if I got a small fridge for $100 or less and drilled 2 holes for the pipes in the side of it and then sealed with silicone and just had the radiator in the fridge, I'm not sure how efficient this would be its only an idea i had in my head but i don't think it would be too expensive and even if your room was 20c your fridge would have cool air blowing through the radiator at 4c

I too have thought of basically that exact same idea. Don't know how well it would work ether. The thing I've started considering more is that most of these "chillers" aren't designed for continuous cooling, they are meant to cool an substance, and then let it stay cool for a while before it boots back up again. unlike a pc which is always producing heat so long as it's on.

After thinking about it for a while the entire project can be summed up into one simple statment:
1. Cooling the computer by taking the heat away from it with out putting it back to the room the computer is in.

I came up with a possible theoretical solution to do this better with out using a chiller.
The PC sits upon a 70" tall cabinet. To the right of the cabinet is the closet door, but to the right of it, on the wall near the floor is a furnace intake vent.
My idea is to put a radiator over the vent's intake (6"x"12) put fans on it that would suck air out of the room, push it thru the rad, and into the wall intake vent. The water loop would have to travel approximately 80" in ether direction.
Thoughts? Could this concept work to cool both the CPU (OCed) and GPU(default)?

This is an incredibly common question across the entirety of the internet (not just on here!), and the answer is always the same - a fridge is designed to keep things cool, not cool them down. Put something that generates heat into one, and you will burn out the fridge.
