I love mine. Most stable system I have ever owned. I don't use the onboard sound though, I have an Audigy for that. I use the onboard NIC, the SATA (RAID 0), and I used to use the VIA VT6410 ATA RAID controller (as JBOD, not RAID 0) before I got my SATA drives. If you won't use the IDE RAID controller, get the non-Deluxe version. I am building another P4 based rig for someone, and I think I am going to build it on a P4P800.
