Using a server psu for mining rig | Bitcointalksearch.org

Hi! I know similar questions is posted before, but i got some questions that i didn't get an answer to in the other posts :/ So, i'm expanding my rig with 30 new R9 280x's. Since these pull a lot of power, so i've decided to use server psu's since these are much cheaper. I'm planning on using 3 or 4 of the ESP120 2900w. I'm following this guys build: https://bitcointalksearch.org/user/sunbreak-21340 , but i've ran into some problems. The first one is; how am i going to connect the 24 pin? I can see that he's using a breaking board that he made, and i'm wondering if i can use this one http://resources.mini-box.com/online/PWR-PICOPSU-120/moreimages/picoPSU-120-small3.gif?. And the second one is; Can i even use this psu? I know it's the output is 51v, but i'm planning on doing this mod: http://www.helifreak.com/showthread.php?p=5710249 and use a 2.5 kΩ resistor to get it down to 12v (is 2.5 kΩ enough?). Sry if my question is confusing, but if something is unclear just ask
