Okey Dokey,
The stuff arrived today (kinda') and I got it all put in and/or transferred. Steps follow:
1) Jumped up and down with joy when "Brown" showed up at 1145!
2) It shipped in two seperate boxes from the same warehouse in Jersey?
3) Unloaded everything and began inspection (I cleaned out the CM Storm Sniper last night to get it ready)
4) Everything looked good until I opened the RAM box. The factory seal on the box and the static bag were both cut and one of the sticks was AWOL

)
5) Logged onto the Egg and opened a chat. A claim was filed (will take 3-5 days to complete, do I want a replacement or refund?) Informed the CS rep that I couldn't wait a week or more for a replacement so requested a refund and immediately ordered some G.Skill Ripjaws with next day shipping. First issue ever with the Egg and I've been using them for everything for a LONG time.
6) Used two sticks of the 6 gigs of tri-channel out of the i7 920 rig giving 4 gig to work with for initial build and testing.
7) Took some pics

Installed everything, transferring GPU, RAM, SSD, HDD, and BD Player from the old rig (took more pics).
9) Plugged it in, said a quick prayer and hit power...
10) Started to boot (the UEFI went by quicker than expected). I was hoping to just have to install drivers going from an X58 to a Z68. Started to load Windows and... BSOD!!!
11) Caught the UEFI setup on reboot, set the SATA mode (defaulted to IDE) to AHCI and saved. Seconds later I was at the Windows logon, albeit at low resolution.
12) Logged on and a few driver installs and reboots later I was sitting at my old desktop!
I must admit that this was the easiest switch of Mobo and CPU that I've ever done! Whole process took a couple of hours and no image restores, repair installs, or complete re-installs required. Other than the RAM issue I am a happy Rabbit!
I still need to tidy the cabling and install the new RAM and the Corsair H100 but I've already ran some basic benches (PCMark and 3DMark Vantage) and there is a performance diff. I also bumped it to 4ghz OC (using just the CPU ratio) and it's stable as a rock with those benches using the stock cooler (not gonna try Prime or full load testing till I get better cooling). Temps stay under 70c running PCMark and are idling at ~34c in normal use so I am fine with these temps and the ease of OCing is a dream.
I'll do another thread with pics and a "Joe User" review this weekend after I've had some play time!
