Building a new desktop PC

[Parabejus]

Hi. I am thinking of building a new desktop PC. I have read some reviews and decided GTX560 Ti for GPU and Intel Core i5-2500 for CPU. Now i'm confused which motherboard should I buy. What would you recommend?
About the proccesor, I found that i5 2500K is better if you are planning to overclock it, so I chose the basic 2500 as I am not going for overclock. Is there a processor which suits GTX 560 Ti better? What would you recommend? I would also like to know how much RAM for such PC would be optimal. Also which power block and case should I choose for optimal power and cooling.
I have somewhere read that H67 motherboard would suit my choice Anyway looking forward to hearing your opinion.

Go for a P67 or Z68 mobo with a second PCI-Ex16 slot for future upgrades. Ram 4-8gb of descent ram would be all you need however if u have more than 4gb make sure u use a 64-bit OS

Ok. But really 2500K? Because I 100% won't use overclock as I want my system to work for about 6 years. Now how many Watts power block should I use? What Else excluding HDD and DVD reader/writer and case and Wireless adapter will I need for my PC? I am also not planning much upgrades. Max 4 extra PCI slots, so should I really buy the MB you mentioned?
