NAS, Server or something else to do with hdd's

Not atom but small

Possible MB:
Gigabyte GA-G31M-ES2L
ZOTAC H55ITX-A-E
Gigabyte H55N-USB3

Possable CPU's:
Athlon II X2
Core i5-661

Under clock it, lower the voltage.

Make sure the case is strong and protects the disks from vibration, they can cause vibrations between themselves that will shorten a the disk life.

should have looked up things a bit more, the Core i5-661 cost a bit more than you trying to aim for, sorry about that

I do not know if there are Atom motherboards (didn't look for them that hard) with 4 SATA ports, but you could use:

a motherboard with a PATA+2xSATA and a couple of SATA-PATA adapters to connect the hard drives
or
a motherboard with 2xSATA and a PCI (or PCI-e, depending on the motherboard) dual port SATA controller.

bork,

A desktop mobo+CPU will use more power than Atom, Geode or whatever VIA offers.

Also, hard drives need to be cooled.

However, a mini-ITX board will fit in any micro-ATX, ATX or EATX case.

I got NEW Idea, how about changing all of 3,5" hdd's into 2,5" + external cases.
Then i can change router with the USB slot one, and make NAS from router.
2'5 need less power suply.

Or buy router + 1HDD 2'5 + case, and store in that drive curently watching films.

Is my idea good? the only thing would be that i would need to make some "safe" place to hold hdd (the 3,5" one) somewhere else (not in pc)
and then need to buy case for hdd to copy something from it when i need it to be "online" all the time.

The idea is surpasses - to many ideas on not complicated thing.

curently:
Router + USB HDD 3,5 case = cheapest but only 1-2 hdd
Router + USB 2,5' case + HDD = cheap but only 1 hdd (currently) + energy saving
normal mobo + psu + case = expensive but unlimited hdd's and allways online
atom mobo + case = most expensive with hdd's limited with psu, but most energy saving.

I see the "energy saving" option is allways more expensive.

I'm currently little confuse :(

Pentium100:
2.5" HDDs are more expensive than 3.5" HDDs of the same capacity :) While 2.5" HDDs need less power than 3.5" ones, a USB port may not be able to provide enough power for more than one of them, so you may still need the separate power supply.

Also, your "router" will most likely be slow as a file server. Watching movies does not take a lot of bandwidth, but if you ever want to move/copy from one drive to another you will have to wait. USB2 limits the bandwidth too.

Anyway, what's wrong with keeping all drives in your main (only?) PC? When I had only one PC, it had 8 drives in it. Well, unless you want your torrenting etc to be independent from your main PC, in which case you need some server.

As for energy saving being more expensive - that's how it is, you either pay now (more expensive components) or later (more energy used).

hmmm.... I would like someone time not to use my hdd's (not turn them on) when i dont need them, and pluging and unpluging them is pain in a..
Other thing is i like to have access to them from few devices and not allways i want to use my main pc as "shearing device"

Probably i will stay with hdd's in pc then. but now i will have 4/4 sata slots and will need to buy SATA controller, but dont know will i will need change PSU.
