Depends on what type of cooling you want. The TRUE (ThermalRight Ultra Extreme) and Prolimatech Megahalems/Ultra Mega are the two best air coolers currently available. But they're big and heavy.

You could also look into a fully-contained water setup like the Cooler Master H50/H20.

I would like to have such cooler which isnt too heavy because I take part LAN parties and need to move my computer. But still it would be good.

Then the H50 or H70 from Corsair (if I may correct sherretz) are good choices. They perform as good or better than the best aircoolers.

But, if you don't plan on overclocking your CPU you can also just use the stock heatsink that comes with the CPU. It's the smallest aircooler you'll find and it should keep the CPU within reasonable temperatures when ran at stock speeds.

And that case supports full ATX, you didn't select exceptionally large components, so my question would rather be, why wouldn't it fit.

thermalright venomous xRT would be a good cooler, i got about a 5c cooler than a v8 and its more lighter too. It also comes with CF 3 thermal paste which is very good. U can put on the bracket and put ur mobo in ur case and then put the cpu heatsink on after ur mobo is screwed in to ur case.

I am interested in corsair h50 but if my case has allreday at the back a 140 mm fan then I just remove it abd replace it with another.

I have another question what would be good ram for this motherboard??
