Hi,

(I apologize in advance if someone thinks this is OT)

I've been reading this thread since it started, and what I could really say
is you should go for freenas, it can be installed in a matter of minutes in
a usb pendrive, I use it on a 2gb kingston one using an IBM eServer tower
chassis, Intel D201GLY2 mainboard, 1Gb 667Mhz RAM, 2 HDs those are 750gb
SATA in RAID5 which are hold entirely for backing up my servers, that
include M$ SQL, M$ Exchange, CentOS LAMPs and CentOS MySQL boxes(about 500Mb
daily using Samba and NFS)this box has been running about eight months now,
also I have another one running on an old Dell P3 using a cheap VIA SATA PCI
card and a CF to IDE adapter which holds 320Gb and 500Gb SATA HDs for my
personal backup and haven't had any issue except for my electrical bill that
increased a few mexican pesos only. The best thing it's you configure all
via web, and there's no need to learn FreeBSD at all.

You should read the Knowledge base maybe it can help you more to make your
mind:

hope it helps,

cu when i cu.
