here is solid translation of complete post. I want it to place this topic in HARDWARE section, and because I am newbie here it is in this section. Sorry about my bad English
My boxes
http://ultraphoto.org/images/f21xdmc2i1s3d3u95rdq.jpgSince I am limited with space (office) that I rented (13 m2), I had to pack all the equipment in the tunnels, by which I ensure stable operation of all equipment. Since I was hiding in the price (60e) is included and electricity use, I decided to MSI 6770 graf.
How do I make it better circulars air (ventilation), I designed a structure to which I have set the motherboard and 4 graphics cards. With the construction of the two power supplies (mainly used one power supply, but again let there be a option for second PSU). Here are some pictures of construction:

http://ultraphoto.org/images/2vhq348q4cputpmffn5.jpgAt the entrance of the tunnel I put 4 fans that will insufflate cold air from the office and also at the exit of the tunnel I put 4 more fans that will erupt through the drain pipe out warm air from the tunnel. I used a brand SUNON fans at 220v (used for server cabinets and endure temperatures from -10 to + 60C).
http://ultraphoto.org/images/3jur8uff7g2d8j33gw33.jpgSince the office has a total of two windows that can open a window to a place I have built a wooden panel (MDF), which I drilled holes for the exhaust of hot air. Since I have a total of four tunnels, I drilled 16 holes on 2 plates. 17th hole is the exhaust hot air from mobile air conditioners.
http://ultraphoto.org/images/pddbwlsd68xc6ufhwxn1.jpgAir is set to 19c, but never really percentages that temperature: lol:
http://ultraphoto.org/images/pz7s3k6tlsdd2m7jv9sj.jpgThere is also an IP camera in order to have an insight into developments in the room itself :lol:
http://ultraphoto.org/images/84hz0qvnb4vda17t41m.jpgThe room temperature is between 25 and 30c, depending on external influences. The temperature in the tunnel is 33 to 40 c. I carried out a temperature monitoring device with the lowest cost, how to have insight into what happens in a closed box.
http://ultraphoto.org/images/gitkmc7xbnfkepk8841q.jpgPower supply for all the equipment I brought over a mini cubicle, where in addition to fuses, timers and set the switches, that when a power failure, or return the current system, have fallen one by one machine, to avoid popping the fuse. In the cupboard I put a switch, that this network cables reminiscent of the Bird's Nest: lol: but also done an excellent job B)
http://ultraphoto.org/images/2jhsrx5l4y5jd42zjx8b.jpghttp://ultraphoto.org/images/gusrx6hgr3yew5v4dtgg.jpgAt the door of the closet have placed 3 amp, so I had the exact extent to which access may be charged once the three phases which are linked
http://ultraphoto.org/images/mf1yy6957nnvrs24z7.jpgAll cables (power and network) are packed in the channels on the side of the tunnel, and brought the ignition switch to the tunnel ventilation system for each individual
http://ultraphoto.org/images/exnuiq3rgpj3ckhxbstc.jpgOn one side of the tunnel were left with the handle hinges to the side of the tunnel could be opened. Here's how it looks when everything is finally closed.
http://ultraphoto.org/images/fn7g9vg6ro4b67l219w.jpgSince the small office area, and the fans at the entrance of a large quantity of air creep, I had to improvise a little extra air flow in the office: lol:
Hopefully this comes to ceilings, and the space above the office I have a steady flow of air beneath the concrete slabs facility
http://ultraphoto.org/images/mhycvxf6w7a5va17kbez.jpgEach structure consists of the following components:
Motherboard: Gigabyte H61M-D2-B3 (1x 16xPCIe + 3x 1xPCIe)
Processor: Intel Celeron G460/G530
Memory: Mushkin DDR3 2GB
Flash: Kingston/Transcend 4GB
Adapters: PCI-e extenders [4 pcs]
Graphics: Ati Radeon MSI HD6770 1GB GDDR5 128bit [4 pcs]
PSU: ThermalTake 675W Thougpower XT
In each tunnel was set at 5 structure (20 graphics cards). It is now in operation about 16 GHS. Temperature graphics from 50c to 70c.
All graphics are in the set 920/300 mhz and let down a voltage of 1.05v to be dropped tempterature graphics cards for at that level.
All machines are under BAMT operating system, where almost all work perfectly
