Do we need to reorder?
No, no need to pre-order again. You will be contacted a few days before shipping starts and everything will be verified again. So no worries.
Pre orders are only to get in line for a case because supplies are tight. This is why we do not ask for credit cards information. You only provide that at the time of payment.
Regarding configuration for best cooling, we haven't run enough test yet but it's kind of up to what you see work best with the heatsink and socket you have. There are so many possiblities, it would take quite a while to test and list everything. However, we are working on a web page that will help you find out what the possibilities are according to you socket and heatsink.
Finally, sorry about the delay in posting pictures of the HDD. I will try to take some shots tonight and post them on the forum.
Thank you to all of you for your support!
