PPC has been great for me too. Really fast shipping, their sales department will work with the vendors to bring in product (They worked with alphacool and bitspower to get products for me). FCPU always seems to be super slow and mega $$ for shipping.
Also, watch out on PPC's facebook page, as they had a 17.5% off coupon a while ago that I got to use. Saved me a ton of money.
