True, and I'm using a trayless hotswap enclosure for off-site backups myself. What I like about the Supermicro cases is that everything is there and you don't have to worry about it. Everything is hotswap, the SATA is already there to support the drives, and it has plenty of cooling and power (frequently redundant power supplies). It is a bit more expensive to go that route, but you know everything is solid. -- Bowie ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
