Homebrew Rackmount Watercooling
Airspirit writes "For those of you who believe that bigger is always better and have multiple computers in your house,
this system may be a way to keep them all cool and organized. As an added bonus, it will heat a medium sized apartment all by itself!
This article at Pro/Cooling gives a step by step walkthrough describing the evolution of this five gallon monstrosity. Not only does this cover the construction of the cooling system, but the drawbacks such as algae prevention and maintenance as well."
What?
Oh, Mountain Dew...
Darn!
You don't need a rackmount water cooler to heat a medium sized apartment, one AMD processor will do quite nicely ;)
And for those who think I'm joking, I haven't run my heater in my apartment since I bought my AMD last winter.

... hate to see the AC bill in the summer though. Especially here where there really is no spring, it just goes directly to hot and humid.
I'd get one if for nothing else but the coolness of it.

Please don't even remind me about homebrew rackmount watercooling... Just remember to always check if the water is not leaking anywhere before you turn it on together with $15000 equipment. This is a lesson I learned the hard way...

this makes you wonder how long it will be before information surpasses transportation as the largest consumer of energy on the planet

Ok, the web site is down. Bring on the traditional

jokes! It has to do with water cooled systems. So,
let's see...
1. The water must be boiling! Har har har!
2. Time for some more coolant! Har har har!
3. The radiator must have blown a gasket! Har har har!
4. Imagine a beowulf cluster of . .
5. They need to switch to a better coolant than water! har har har!
Oy, this is sooooo predictable. Mod this down because I
close with a traditional "slashdot sucks" comment.
I'm looking at the green water on the diagram and I see the blackish smudge and I'm wondering if that's a plecostomos???
Now I suppose someone's gotta code Perl::FishFeed to make sure the algae prevention measures are in place....

Algae prevention is a drawback? Remind me to never eat from the submitter's refridgerator.
Trolling is a art,
" Being that I'm in physics and I barely need a home computer, I'm always mystified by people who have things like rack-mount systems in their homes. I never manage to understand why you'd need that sort of thing."
;-)
Oh, music, movies, games, web, chat, photos... you know - fun!
You, dear sir, are trolling. Plenty of people need lots of power in house. Some like to do 3D artwork which requires a lot of power for rendering. Others yet work at home, serving their websites and the such, and want to keep their computers managable and neatly tucked away somewhere so that their spouce doesn't lash them for all the cables running everywhere. I'de have a rackmount system myself if I could afford such a thing.
;).
I just feel sorry for the poor guy. The heat must get unbearable when those things start churning. Maybe he should use the water cooling system to cool himself off instead

Why prevent the growth of algae? With algae, this object fully supports your personal biosphere.

Argh I saw homebrew and excitedly clicked in because I thought it was a way to keep the PC cool while brewing your own beer. Boy was I surprised.

You are bound to have the following happen.
1.) Be marked as overrated, troll, or offtopic to a -1 karma
2.) If someone other than me does reply they will either mention the FAQ, or provide you with a link.
3.) Someone will actually "tell" you what the FAQ Says
Slashdot should cache pages to prevent the Slashdot Effect!
Sure, it's a great idea, but it has a lot of implications. For example, commercial sites rely on their banner ads to generate revenue. If I cache one of their pages, this will mess with their statistics, and mess with their banner ads. In other words, this will piss them off.
Of course, most of the time, the commercial sites that actually have income from banner ads easily withstand the Slashdot Effect. So perhaps we could draw the line at sites that don't have ads. They are, after all, much more likely to buckle under the pressure of all those unexpected hits. But what happens if I cache the site, and they update themselves? Once again, I'm transmitting data that I shouldn't be, only this time my cache is out of date!
I could try asking permission, but do you want to wait 6 hours for a cool breaking story while we wait for permission to link someone?
So the quick answer is: "Sure, caching would be neat." It would make things a lot easier when servers go down, but it's a complicated issue that would need to be thought through in great detail before being implemented.

4.) Someone might actually answer your question ...
Basically it all boils down to slashdot doesn't care if it causes an effect similar to that of a denial of service attack. They feel that since they are linking to a public webserver that they are doing no more harm than say a search engine. The caching of a webpage would mean that they would have to invest time and technology into a caching system (which they have neither the programming experience or capabilities) and not to mention money in the hardware (gotta store the things).
It's a weird situation, slashdot publishes a story acknowledging That there are smaller servers that never intend to have the amount of traffic that they get. Just so happens that no one has actually sued slashdot yet, which happens to be the only thing the editors fear more than being fired.
So will you see a change, no, and why? Because of the above mentioned reasons and because those responsible for building slashdot are lazy and not innovative. You want innovation and caching then I would highly reccomend google. Just post in the subject line of most slashdot stories, since most of them are usually a week old, they've already been cached.
Ignore the "p2p is theft" trolls, they're just uninformed
Every time I see a slashdot headline with the word "homebrew" in it I think that at last there's an article about beer, but no :-(

It must be time to go to bed. I just worked all night and at first I read "Hebrew rackmount cooling." I was so confused.
Warm water breeds all sorts of wildlife. Use waterbed disinfectant in there (or a small amount of bleach) to keep things clean.
The trick then is that the water containment needs to be waterproof sealed, otherwise as the water evaporates, you'll have chemicals floating around in the air of your house.

This is actually my system. I don't think Joe, the owner of Pro/Cooling (not hosted on a watercooled system, btw), had any warning that his server was about to be slashdotted. I suppose spraying your systems down with a fire extinguisher is not the best way to spend a Monday morning, but who am I to judge?
... oddly enough, she uses Windows for the "heavy lifting" and Linux because she loves the games!).
And he always said he wanted more traffic, hehe.
Anyway, the reason I have so many machines is that I do professional web design and database programming, an obscene amount of gaming, and host multiple network services. From top to bottom you have:
PC 1: Gaming, development (WinXP/Mandrake 9.1)
PC 2: Wife's office computer (WinXP/Mandrake 9.1)
PC 3: Linux network server
I host a mini-ISP out of my house for the neighborhood, so the Linux server helps keep bandwidth consumption down as well as providing other services my customers demand.
I have a KVM that allows me to swap between PCs 1 and 3, and she has her own equipment for her PC (I just leave it alone
Anyway, I better go run and hide before Joe hunts me down!

Yoshi DeHerrera of TechTV has an article about how to use HFE from 3M to build a submerged cooling system for a computer. Find it here.
Check out the Google Cache of the page
Here is a link to Yoshi's Submersion Cooling Case. They used hydrofluoroether (HFE) from 3M.
...so that their spouce doesn't lash them for all the cables running everywhere...
That is the reason why I don't have a rackmount system.

..how this works." "The white stuff requires two types of glue to form a seal. First you apply primer, rubbing the brush around until the PVC starts dissolving and looks milky (do this on both parts on all areas that will be connected), and then you apply PVC glue until the primer and glue are completely mixed (on both parts).." You don't /mix/ the primer and glue! The primer is a alchohol-based cleaning compound! If you don't wait until it dries, the joint won't bond.
".. and then you slide the parts together and hold on for dear life."
Hell yes! He mixed the glue and primer: "Pal, you're going to be holding that for a loooong time.."
Oh, and I /do/ work with Sch 40; think 200 psi pressure lines. Don't mix the primer, man. It ain't purty.

I've got conduit running from the second floor computer room in my house into both the attic and crawlspace. I'm thinking of doing something like this, and running the heat exchanger portion under the house, to take advantage of the cool climate under there, and provide and emergency outlet for leaks. I'm thinking of using copper tubing on the two heat-exchange ends, with polymer tubing in between (in the conduit). I'm wondering what the flow rate would need to be, and how big the tubing would need to be to support that flow rate. Not being a fluid-flow or heating/cooling engineer of any type, I'm posting this question. :) It would be convenient to be able to use ordinary fish-tank equipment. The height of the water loop will play into that -- it has to be pumped up and down about 20 feet.

I invested in rack mount cases and an enclosure a few years back, and haven't regretted it. If you have little floorspace and need several machines, racks can't be beat. They use airspace that is otherwise wasted. Mine uses a closet.
But God Allmighty, it's not cheap.
The exception is if you use a large ventilation fan to blow into an open case. (been there done that.)
I DO use my computer as a whitenoise generator at night though. I've seen people charge $100-200 for whitenoise generators, when a simple program on a PC can do the trick. Under Linux, do a search for "whitenoise". Nice small program.
Under Windows, so far the best solution I have come up with is to use Octave to generate a white noise (actually, "pink" noise, i.e. white noise that has been lowpass filtered) waveform, save it to .wav, and set Winamp to play it in an infinite loop.
Octave code to do this:
This creates white noise at a high level up to abour 2.2 kHz, and then additional noise at a much lower volume up to 4.4 kHz or so. You can adjust the cutoff frequencies (Second arguments to both fir1() functions and the ratios of volumes to your preference.Note that I generate a noise array and then dupe it three times before filtering it and then truncating it again. This prevents discontinuities in the final waveform that would present audible clicks/pops after every loop. (Similar theory to some of the tricks used to make seamless tiles in The GIMP.)

I use 8 parts distilled water, 3 parts "G12" (pink colored) VW/Audi/Mercedes engine coolant* and 1 part denatured alcohol.
I've been algae and critter free** for over year now with no maintenance required at all.
* This is probably the best coolant you can buy. It is free of all corrosive chemicals that "regular" coolant has, and it prevents corrosion due to dissimilar metals better than other coolants. ** My PC watercooling rig is pristine and clear and free of bacteria and algae and small animals. If it weren't for the toxic coolant and alcohol, I could drink it.
I'd rather be a conservative nutjob than a liberal with no nuts and no job.
Hey, wait a moment.
You make noise?
I mean, you MAKE noise so that you can sleep?
Hell, I turn off my Apple/PC to have NO noise.
And I live in the middle of town.br.
I don't claim to be a scientist, but one thing struck me when I was reading the page about your project. At the end you kind of complain about the ambient temperature in the room from your cooling system. But you also complain that your stage 3 temperatures were higher then your Stage 2 temperatures. Yeah, I'll bet. If you really want to know what is just from the cooling system you have to adjust the room temperature so it is constant.
I mean, it it's the winter time in the first example and your temperature is low, but your room temperature is 65F, then that's one thing. But, if your temperature is high and it's the summer and your room temp is 85F then that's something else entirely.
It seems to me it's possible you have an uncontrolled variable roaming around destroying your data.
