[CentOS] OT: Home NAS device

I am looking for something that I can hack away like a NSLU2 but that thing only has one disc
and worst of all its 100m interface. Anyone know of a device you can load Linux on that has
maybe 2 discs like a NAS200 with a gig nic? I need a quiet device to act as a tftp-dhcp/web/dns
system.

I thought of just building one from a new Soekris board, or even a mini itx but hope there was
something simpler/cheaper.

Thanks for any reco's!
