I was thinking to build an home server. What I focus on the most is low power consumption.
It should be able to run CentOS with a webserver, a trasmission client, host git repos, and maybe a DNS server for my local network.
Storage is not important since I already have more than one NAS.
I was inspired by this article and wanted to use it as a guideline. The case used in the article have 2x2.5"HDD bays, so i thought about 2x 320 or 500GB 7200RPM HDD, connected in RAID 1.
But, I wasn't able to find a mini-itx motherboard (in a reasonable price and power consumption range), that could support RAID.
Another option is using one single SSD, which should be more reliable than an HDD, and should use less power.
Are those two assumptions right? Is it ok for a server with that scope use an SSD (i can backup important files on one NAS, and since it'll host git repos, those will be also on 1-2 more pc).
And one more question: Is an Atom CPU capable of running a web-server, a DNS-server, and a bit-torrent client simultaneously?
Thank you in advance for the time you took reading, and for your answers.
