-====== 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.
