Yeah I did find that. 35w sounds ok, although there will be about 25-30w of disks in it so it'll probably end up higher. Debating what disks to get, either WD red 6/8tb or maybe those new Seagate 10tb. Will probably go for the 6's as a balance of rebuild time vs cost. Unbuffered ecc ram is unfortunately uncommon so will be about £120 for 32gb. Then there's choosing a storage controller - I may get another m1015 although somewhere i do have a spare 9750-4i, but it does run hot.
