Caviar Blacks are 7,200 RPM drives. Perhaps you were thinking of the 5,400 RPM Caviar Green?
Overall, it's a nice build that would be pretty well-balanced if someone decided to purchase another 6850 or 6870 to do crossfire with for gaming. You may have some trouble selling without feedback or some sort of trader rating.
Regardless, good luck with your sale.
Just checked my Newegg order invoice, it is the 7,200rpm Caviar Black.
Thanks, I appreciate it. My purpose was to build a PC that used only high quality components, was easily upgradeable, and would of course last for a long time. I built it when the Core i5's were first released and its still very fast, the only thing that has slowed down is the HDD which are known to over their lifetimes.
As far as that goes I have an Ebay account with moderately low feedback(17) but all positive. I also have feedback from a card trading site with 27 feedback and all positive.
Also, Paypal is VERY favorable towards buyers and usually hold payments to sellers until buyers receive their end.
