Hi all, just joined this group to hopefully get some help. I am building a pc for the first time and just want to check my build. Theres a couple of things im unsure about and want to get it right first time.

CM Storm scout case

OCZ Fatal1ty 750W PSU

AMD Phenom II X4 970 Black Edition 125 Watt Socket AM3 3.5GHz 6MB L3 Cache Retail Boxed Processor

Asus M4A88TD-V EVO/USB3 880G Socket AM3 8 Channel Audio ATX Motherboard

G-Skill 4GB (2x2GB) DDR3 1600MHz/PC3-12800 Ripjaw Memory Kit CL7(7-8-7-24) 1.65V

Western Digital WD6402AAEX 640GB Hard Drive SATAIII 7200rpm 64MB Cache - OEM Caviar Black

**EITHER** Noctua NH-D14 or Corsair H70

5850 Graphics card

Win 7 64bit home OEM/LiteOn 24x DVD/LG 22" Monitor


My questions are:-
1/. Will the RAM be okay in that motherboard?
2/. Which cooler should i get and what sort of OC will i be able to get with medium temps?
3/. Will i notice a difference with the SATAIII hard disk?
4/. In the simplest terms what is RAID
5/. Where can i find a great guide to OC for absolute begginers?

Many thanks in advance x
