Corsair 8GB 1600MHz PC3-12800 CL9 DDR3 Vengeance Memory

Are there any bottlenecks/possible conflicts from preventing opptimal performance
Also, what are the prospects for overclocking?

Asrock doesn't offer industry standard 3 year warranty

The Corsair water coolers are noisy and not that great compared to the better air coolers

OCZ XStream PSU's are not very well rated.
