But how do you know if it's compatible with the following servers?the QHUZ is a 20 Core ES2, but low frequencies as almost all ES2.
you should look out for a 18 core E5-2695 v4, with same or more performance as a 20 core ES2.
they go from $200 - $250 at ebay, sellers form north america too.
the QS is not much cheaper, goes from $180 plus ship&fees.
