I wish I could paste in my spreadsheet and not lose all the formatting since I ended up purchased most parts at Newegg, but a few locally at MicroCenter as well as BestBuy. I bolded the price that I paid and you can line it up with the 3 locations at the top of the data.
Yes, Bestbuy! They had the best prices and selection on keyboards and mice. Otherwise, their prices are nuts vs. newegg. These prices are net to newegg and don't include rebates. Total cost right around $1500 after rebates.

Everything came from newegg except for the case, CPU and monitor (and keyboard and mouse as already mentioned). Reasoning was 1) I could see and touch the case before buying and I knew it was in good shape and not damaged from shipment. I read a few reviews of cases on newegg.com that were damaged in shipment and the price wasn't that much differnt. 2) CPU was much lower at MicroCenter. It has since risen to almost the same as newegg. 3) Monitor, again I wanted to see it and so on. We will test and return if its not real sharp (some reviews online gave it lukewarm reviews), but its the best 22" bang for the buck.
Otherwise, newegg had great prices and information. Hard to beat so far, but this is my first majoe purchase from them. Every other purchase was minor. So far, so good.
