The challenge:
since in february my daughter was born i figured out that i can't afford more than one system in the house. So i sold the skulltrail platform and get a Classified board a good cpu some GT Dominators and a pair of 295GTX single PCB. Actually i use a Lian Li PC-A7010B case with one XSPC RX480 for the cpu loop and a 240GTX for mobo. When i'll get the epsilon blocks i intend to mount a second 240GTX on the back of the case and hook up both videocards to the mobo loop. I think that 2 GTX240 rads will be able to handle the mobo + the two videocards at least at stock speeds. I the mean time i started to think about a custom case which will be able to cool any hardware in the next 2 maybe 3 years. I'll present my thoughts and i hope that you guys can tell me if this setup worth it.
Basically what i have in mind is a radbox which will house two MO-RA radiators. Each radiator will be cooled by a single fan from EBM Papst P/N: W3G330CA5802. (detailed specs here (http://img.ebmpapst.com/products/datasheets/W3G330CA5802-ENG.pdf)) I use these fans on a daily basis in industrial automation and i like them very much because you can control the speed using 0-10v industrial control. As i read some reviews regarding these radiators i found out that they are pretty restrictive so my only option is the Iwaki RD30 pumps hooked up to a custom reservoir. For the control part i intend to use a spare Unitronics PLC the V570, together with some expansion modules. I like this type of PLC because you can do whatever you want with them. The V570 will have the following I/O config:
2 analog imputs (4-20mA) which will get data from the two IFM SM6000 electromagnetic flowmeters installed in the system one piece for each loop (detailed specs here (http://www.ifm.com/ifmgb/web/dsfs!SM6000.html))
2 analog outputs configured as voltage outputs to control the EBM Papst fans
4 PT100 imputs for temp probes which will be installed at the entrance in the radiator and exit of the radiator
2 High Speed imputs for tacho signals from the EBM Papst fans
8 Relay outputs for various mobo functions (Power, Reset, Clear BIOS etc) for easy control of the mobo from the touch screen.
8 Digital inputs for various stuff.
The PLC will monitor the fan rpm, the water flow and a bunch of other signals and if something is wrong it will shut down the system. Also the fan speed will be controled by PID in accordance with the cooling fluid temps monitored by the PT 100 temp probes.
For the plumbing part inside the radbox i intend to use copper pipes instead of tubing because the config inside the radbox will be permanent.
For the moment i'm in a business trip and i have only the laptop with me but as soon as i get home i'll start designing the case in solidworks and i'll came up with some pictures. a simple schematic looks like this:

The mobo will be installed in a custom plexi case on top of the radbox for easy access and high bling factor :)
I'm open to any comments and recomandations. Feel free to post any thoughts you have regarding this concept.
L.E
EBM Papst fans are on the way.
V570 and expansion modules already have them.
Radiators will be ordered next week i think.
What i really need is two Iwaki RD30 pumps (i prefer the japanese model)
Few pictures with the actual build:
