Build Advice NAS upgrade help please

I have a NAS-type file server I built last year using an old P4 system I had and Ubuntu Server 10.04.

It's been working fine, but I would like to update it with a less power hungry and quieter CPU/Mobo/RAM combo.

It's mainly used as a file server via Samba for images, video and music to the other PC's on the network, and as a backup location for those PC's too.

Current build (from memory):
CPU: P4 560J 3.6GHz Prescott
Mobo: MSI 915-GM
RAM: 1GB DDR
HDD: 2TB WD (can't remeber exactly which one)
HDD: 300Gb (Can't remember what make)
PSU: Seasonic S12II 380W
Case: Old beige ATX case
OS: Ubuntu Server 10.04


I'll keep the PSU, case and HDD's and get new CPU/Mobo/Ram.
I've been looking around and think that a Sempron 140 should be fine for my purposes. It might be nice to get a mobo that could unlock the potential 2nd core, but it's not essential.
It's hard to find reviews on AM3 boards that aren't aimed at high end users, so I don't really have much idea about what is a good choice. Also, my last couple builds have been Intel, so i haven't kept abreast of AMD offerings.

What I would like:
mATX - possibly will upgrade case at some point, and want smaller options. Don't need iTX though.
I would like 5 or 6 SATA ports, not too fussed about v3.
Gigabit ethernet for when I upgrade the router.
1 or 2gb RAM
Onboard video
Will boot without keyboard plugged in - current one refuses to boot without a keyboard.
Works with Ubuntu 10.04


Can anybody suggest some suitable motherboards, please? Or alternative CPU's/Mobo's if you think I'm going completely the wrong way with the Sempron?


Many Thanks

 

the ASUS E35M1-M would be my top choice for a matx server build. it costs about the same as a sempron and midrange motherboard. already dual core and a very good feature set.

 

That looks interesting - I like the passive CPU heatsink!

Anybody have any other options?


Thanks

 

Anyone?

 

This pretty much. Should be loads.

Beige case? Eww

 

Thanks, always good to get confirmation

Is it worth paying the extra £7 for the PRO version which has USB3?

Yeah, but it was available and it hides in the corner of the office (aka 3rd bedroom).

 

Thanks to both of you

I will go for the Asus E35M1-M PRO and I intend to keep it for a good few years. (Won't have any spare cash for PC's after children come along)!

 

No problem mate. Hope the build goes well.
