FreeBSD - software raid

[Moti Levy]

Hi,
before I do the unthinkable and use Linux for a server , I ask for your
help.
I have a set of 4 IDE drives .
I need to build a file server that'll run samba/nfs

I want to use all 4 drives as a raid 5 array and use the combined space for
storage.
is there a way to do it with FreeBSD ?
I looked at ccd and vinum but as far as my understanding goes , I cant use
it during setup but rather build the
system first and than use ccd/vinum on all BUT the system disk .
am I wrong ?
is there a solution out there ?

thanks
moti
