If you're willing to go micro-ATX your choices expand considerably, as there are quite a few decent micro-ATX boards on the market with 5 or 6 SATA ports. Buy an efficient PSU, put a low power CPU in there, and enable CPU power management, and your power usage should be pretty reasonable.

Sound realistic //:) NAS typical follow by slot of HD , USB slot and last is the LAN too.
Is there any good case + motherboard for this ? I will like to have a NAS where it dont have bottlenet in term of IO , CPU wise i think Intel is much in favor..(I'm an old AMD timer)

There are some interesting Mini-ITX motherboard+CPU options.
The $125 Asus E35M1-I has six SATA III ports with the appealing AMD Zacate E-350 APU.
The $187 Jetway JNF99FL-525-LF has six SATA II ports with the Intel Atom D525 CPU.
The $140 Zotac H67ITX-C-E has two SATA III ports and four SATA II ports. Its LGA1155 socket would accept a $57 Celeron G530 or other Sandy Bridge processor.
Nearly-universal 1x4 GiB for $20 or 2x2 GiB PC3-10600 for $24 or 2x4 GiB PC3-12800 for $40 (CAS 9, 1.5V) 240-pin DDR3 desktop memory should work with the Zacate and Sandy Bridge options, but the Atom board would require 2x2 GiB of 204-pin DDR3 laptop memory.
Even a small energy efficient ATX power supply like the $48½ SeaSonic SS-300ET is likely to be overkill for this low-power application.
In micro-ATX, there are many possibilities. A micro-ATX tower case like the $118 SilverStone Temjin TJ-08E (reviewed here) or a flimsy $35 case could do the trick.
Zacate still offers an appealing low-power solution like the $127½ Asus E35M1-M Pro with included E-350 APU.
You could consider Llano in socket-FM1 like the $120 Asus F1A75M Pro with a $50 A4-3400 or $45 A4-3300.
You could consider socket-AM3+ like the $112½ Asus M5A88-M with a $65 Athlon II X2 260.
You could consider Sandy Bridge in LGA1155 like the $130 Asus P8Z68-M Pro with a $57 Celeron G530.
If you don't already have some old parts lying around to re-use, either Zacate or Sandy Bridge would be the most appealing option.
Atom is slightly slower and much more expensive than Zacate while using slightly more power, so there's no good reason to consider Atom for any applications anywhere. Socket-AM3 processors are more power-hungry than Sandy Bridge. Socket-FM1 APUs use less power than Socket-AM3 CPUs, but you don't really need the graphics performance that Llano provides.

I have a not-quite NAS setup here using this atom motherboard + Arch linux running a RAID array of 1 TB drives. It's a not-quite NAS because my main PC accesses the drives using ATA over Ethernet (AoE) instead of a network share like NFS or SAMBA.
It is extremely stable and quite fast. I use a pair of gigabit network links that run in parallel using the AoE software. I use suspend to RAM on my main PC to save power when I'm not using it, and the main PC comes back up every time (I've been running 38 days since my last kernel upgrade). The Atom is not a speed demon, but it can saturate 2 Gigabit links from the server to my main PC using software RAID-5 in Linux, so that's good enough for my purposes.
The Atom board I'm using is a little bit older now (bought it in early 2010) but it is fanless, has a PCIe expansion slot, and has 6 SATA ports that I am using for 3 HDDs in the RAID array and 1 old SSD that has all the system software. If I were to build a system like this today I'd probably grab an integrated bobcat board as long as it had lots of SATA ports and a decent disk controller.

With slow fans, the only thing you can hear are the hard drives thumping away. Power consumption is under 100W. These components are all obviously obsolete now, since I built it almost two years ago, but they've all got modern counterparts.
