Mobo's..... Only real advice I have is to get something with good solid state caps, MIL-spec 2 or better.
Power delivery kills gaming rigs, if you buy a cheap mobo and overclock anything, your VRM's also need good cooling. Bad capacitors and hot VRM's destabilize overclocks even when things are operating within specs.
Cooling: this is essential, biggest debate is aircooling over water, I say, use both.
A good cheap "closed loop" water system does wonders for cooling your proc... and overheating the rest of your internals, unfortunately.
I use a Corsair H-60 1st gen, they cost about 70$ many brands have units in that range also. your water system will prolly last you a couple of builds, so get one you like.
Next you would want large low RPM fans, 120's, 150's, even 200mm fans are good choices, you would also want to look at the decible rateing, 27.5 Db is a good medium, its going to be quieter at low speed anywayz. fans can be had for 5$ even with leds <woot woot> just be sure to check your decible rating (Db).
dont forget thermal paste! best stuff out right now is artic MX4, tube can be had for 8$
Let's face it, having a fast PC is awesome, hearing it fire up and sound like a turbine is great, until about hour 2 comes along and you have a migraine =/
amd,intel, nvidia or ati... keep it cool and quiet and youll be a much happier gamer!
