The CPU is OEM. Basically, OEM CPUs don't come with a cooler and have a 1 year warranty instead of 3 years. You don't need a CPU cooler as you're buying a better one, which leaves the warranty, I tend to find CPUs don't go wrong, especially if you don't overclock them, but it;s up to you, the extra money isn't a great deal, but if you're on a strict budget, you have to consider it.
I heard the retail version is still B3 sometimes. So I'm going to go for the G0 OEM version. Once again, THANK YOU, to both of you
Good stuff, I'm also glad to see you spotted the stepping differences, I wasn't aware B3s were still being sold in the US. Good luck with the build, any questions, you know where we are!
Well, have a look around. I presume you're probably sick of the disarray that is the official thread...
This is the (cheaper) non-Dell version of that PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16817703015&Tpk=PPCS500
