Meh, I am also on a quest to get the 3500+. I saw on Sunday (8/22) that ZipZoomFly had some 3500+'s in stock, so I put in my order for that, a motherboard, and RAM. The next day when I go to ZipZoomFly's website, I see the processor out of stock, so I think "Ahh, crap... " but check my order status and see everything in my order was shipped, tracking number and all. Well, today I open my order, and to my suprise... I have the motherboard and RAM, but no processor! And on the invoice, I see "B/O" written on the invoice, and the processor is highlighted... gahhh, back order!
Meh, kinda frustrating... I was hoping to build that rig today. I called ZZF and he said they're getting some more in today and I should have my processor here next week. I hope I can trust his word.... sounds like these processors are hard to get.
