What hardware do you own that is not supported?

While it can certainly be done with CentOS, I'd take a look at  
Solaris/OpenSolaris for that purpose.
ZFS really beats anything else out there.
But you need a lot of RAM. 2 GB is good, 4 GB would be better ;-)
Actually, the calculation is that it needs a GB of RAM for every TB  
of managed data.
So, if RAM is scarce and the feature of ZFS are not needed (for  
whatever reason), CentOS may be still be a good option.
