Default Watercooling a Shuttle

Hi all, I am new here and totally amazed at the technical level you guys are working at.
Now for my problem, I am totally new to water cooling and trying to do it in an SFF machine brings slightly different problems, which I hope you guys can answer. I want to keep everything internal and looking to keep temps down rather than ultra quiet.

Due to space restriction a very small pump is required to fit. The AquariusII kit is what I was thinking of starting with. The pump spec is:
Water Pressure: 1.2 kg/cm2
Pump Speed: 90 L/hr

Obviously this is quite low. Being a machinist by trade with full workshop facilities including CNC, what design of water block would you propose for a system with low flow rate, that I could either buy or make that would make the best use of this.
Otherwise could you recommend a very small pump that would be a better starting point.
Thanks in advance, guys.

First a little conversion...

1.2 kg/cm^2 = 12 meters of water, or 39 feet H2O.
Pump speed (flow actually): 90L/h = 24 gph = 0.4 gpm

(Thanks to http://www.convert-me.com )

That's quite a pump!

The pressure is way above what we normally use, usually coming from a magnetic drive pump. Are you sure about those figures?

Othewrwise, I'd refer you to the #Rotor water block (search here): perfect for you, unless you want to get into some fancier CNC work.

They're what thermaltake quote but they do seems somewhat overstated for a 2W pump.

In germany we just had a case Modding Contest sponsored from shuttle. Most of the mods were of course watercooled. maybe you can get some inspirations from there:

here is the link to the forum:

another german watercooled shuttle (it semms that it is pretty "in" today to cool mod a shuttle):

CPU, VPU and nbcooling is no problem for a shuttle. the bigest problem is the radiator. the aquarius2 rad is not able to reach performance levels like a Thermalright slk or sp cooler, because it is simply too small and has not enough surface, not dependend on the quality of cpublock and pump.
also a dual80 radiator is still worse than a good heattransformer 2 single 120mm rad.

I attached a few nice pics of the modded and watercooled shuttles.
Just some informations: The shuttle in the first pic has watercooled following components with selfmade copper/acryl blocks: Processor, Graphics card, Graphics card RAM, graphics card voltage regulators, northbridge, voltage regulators of the board, southbridge, ddrram, power supply

The pics are property of pcmax and crazyD (first 2) and Overclocker (3rd pic), just to mention it.

I hope i could help an give you some inspirations with these links

I was in Halfords (car spares and stuff in the UK) and i saw a load of small pumps that operate the washer jets on cars. They are really small and operate on 12V. i have no idea on there outputs but it could be worth and experiment, although they may be a bit load.

Probably won't handle continuous use without wearing out...

Washer pumps aren't usually rated for 100% duty cycle, I'd go with a small aquarium pump of some sort.
