@Plec, I have only started messing around with RAID arrays, so I hvae only tested these 2 raptors in RAID0.
I will have a read later today about RAID5 to see how that could benefit me.
I was up til 4AM this morning putting all my hardware back inside the case, I spent ages trying to figure out the best way to manage all my cables, but it still isn't 100% due to the design of my case, but I will be ripping it all apart again soon to have the work done to my case, so it will have to do for now.
I don't think I did to bad of a job really, it is a lot better than it was the last time I had everything inside the case.
I'll get some pics of my rig up here later on for you guys to see.
It was left running Prime95 Blend Test last night with the 4GHz o/c and it was still going this morning, I only just stopped the test 5 minutes ago, and it does 20 passes of LinX using all available RAM to, so I would say this is stable.
@mothermachine, that's good to hear you will be getting the Megahalems as a replacement for your Noctua, it will perform a lot better I should think. Hopefully they give you a couple of Akasa Apache's to hook up to the heatsink, those fans are supposed to be amazing.
