I have a board works 8 slots server a delta.
Got it at alibaba.
I felt seller was sleazy
and the board that came was a little different then to board that was pictured.
This made me not want to order 10 more.
I also cost 30 more then the Onda.
I have been able to run the onda with
set 1070's at 110 watts and use some 1989 tis at 200 watts

http://www.corsair.com/en-us/rmi-series-rm1000i-1000-watt-80-plus-gold-certified-fully-modular-psu-na-refurbishedI also found the onda is good with 7 cards rather then 8
that allows me to use the rm1000i psu at under 800 watts
so the psu is 149 which is now cheaper then the delta by 40
the board is 30 cheaper
so I save 70 with the onda and 7 cards
if you had 56 cards
generic from sleazy guy 7 boards of 8 cards so 7 x 70 = 490 more
onda you need 8 boards so
ram 40
cpu 100
board 170
total 310
so the onda is cheaper running 7 cards with the corasir
and the generic cost more running 8 cards with the server
if you could get the deltas for 165 and not 190 the generic would cost the same
but I would still worry about the seller
Is buying from alibaba as safe as buying from ebay? saw something on that site I was interested in buying but not sure how good the buyer protection is or if theres any
Also I'm wondering about aliexpress
