Hi guys. I want to build a case that is closed on top because i will put my flat screen on it but I need air cooling still.

Is it a problem if i flip the motherboard upside down to bolt it at the top of the case and make a ram air tube or buy one that will suck the air under the case? The bottom of the horizontal case will have one 120mm hole for the psu fan, one 80mm for the cpu ram air and i will bolt around at the bottom the psu, the hdd and the dvd burner.

:confused:
 
No problem. Check to ensure things like video cards are staying properly in place.

I'm guessing it's important to you that air be taken in from the bottom, or you would not be planning this way—but there's also the more conventional design with the motherboard on bottom, top side up, with intake and exhaust fans in front and back respectively, blowing air across the motherboard. Basically your standard tower chassis on its right side.

I want the case to get the air for the CPU from the bottom since the hot air is on top of fresh air based on physics law ;)

Also less noise by putting fans that way. The air will blow out by the psu fan, will blow in the ram air of the cpu and will blow in from the back with a ram air to cool down the north and south bridge.

2 X 80mm intakes and one 120mm exhaust.
 
To truly take advantage of the natural upward convection of heat, you'd want to design a case where the back of the motherboard (with all the IO ports) is placed at the top of the case, as on the Silverstone Raven (which has proven through its excellent acoustics and cooling performance that the idea has serious merits).
 
don't use a really heavy heatsink or you could have problems..
 
I'll stick to oem cooler will just change the fan :P
The mobo will be placed horizontally with I/O ports on the back.
and the back will be used as the place to put the intake for the chipset.
