 +====== New NAS ======
 +
 +I've put hand on a SAS/SATA Backplane from HP, since i already have a Smart Array P400, i will make a try working on a new NAS.
 +\\
 +\\
 +Now : The NAS is an ATX Tower, pretty big, with 6 to 8 hard drives, 3"1/2 and one 2"1/2. it makes noise and vibrations.\\
 +Wanted : A compact NAS, with two PSU, 8 2"1/2 hard drives, and noise-less.
 +
 +===== Stuff =====
 +  * PSU : Compaq PS-5141-4C - 145W
 +    * Will be used only for motherboard. One of the 12V line will activate the relay for the second PSU.
 +  * PSU : EMACS P1A-6300P - 300W
 +    * Will be used only for HDDs backplane and fans, the shunt beetween green/black will be done by the first PSU.
 +  * Backplane SAS/SATA HP : 8 HDDs 2"1/2, i have two of them, one will be sacrified for pinout reversing
 +
 +===== Disks =====
 +8 disks in 2"1/2 size, i think i already have one 500Gb somewhere.\\
 +I plan to use only 500Gb drives, as they are cheaper and easyier to find in scrap.\\
 +Maybe if someone have eight 1Tb 2"1/2 hard drives to throw, i wont say no... ;)
 +
 +===== Backplane =====
 +  * http://​forums.overclockers.com.au/​showthread.php?​t=1094947
 +  * And according to another source i dont remember, the following match the link.
 +
 +<​code>​
 +_______clip________
 +5v_|   ​|GND| ​  |5v_
 +12v|GND|GND|GND|12v
 +</​code>​
 +
 +===== PSU =====
 +  * The first will power a relay using 12V line to power-up the second
 +  * Power connectors will be moved
 +  * The motherboard PSU doesnt have a "​P4"​ connector, i will sacrifice the two molex 12V lines to create it.
 +
 +===== Fans =====
 +  * CPU Fan will be changed, need a low profile and noise-less
 +  * Two big fan, with speed regulation by hand, mainly for HDDs
 +  * Fans of PSU will be probably changed, biggers, less noise
 +
 +===== Other =====
 +  * Two USB sockets will be fixed inside, one for the FreeNAS USB Key, other for... i dont know
 +
 +===== Casing =====
 +I dont have actually any ideas in what to put it. I will look in military surplus or old RF/​Measurement equipment to find something at least 20% cooler to use.
