The 32GB figure made sense to me as I've actually seen the (2 x 16) modules for sale...albeit at about a $300+ price range. (I'm not in any hurry to build this machine.)Actually I saw at Frys where they had 32GB on sale for half that, but don't know if it was (2 x16). Most likely it was not. Funny thing is I was hoping to shop for something with a little more capacity anyways: something I could start of by putting maybe 8 or 16Gb in and then increasing later.

Now according to my understand, with a mb having more than 2 memory slots, it's not necessary to fill all the slots in order to use the board, correct?
