The BF/CM are big discount sale, but not all the parts will on sale. You may need do the cherry-pick for your parts.
I recommend to buy the case, DVD drive, cpu cooler, case fan if you need more fans first, then buy the rest on those sale.
I think the DVD in newegg.com for $15 that is the good deal. http://promotions.newegg.com/neemail/latest/index-landing.aspx
