It's fairly easy to be honest, hardest bit is fitting the power cables around it.
if you need any guidance with any bit let me know, I have re fitted mine about 4 or 5 times now.
What CPU did you go with in the end then? 1090T/1100T?
Thanks JAG, in truth you are right. The fitting of it was fairly straight forward and the back plate was actually a lot easier than I was anticipating. I'm very thankful for my HAF X case, gives me plenty of room. And there is only two leads from the V10 so the cable management has been easy.
