Ok, i was thinking of upggrading my harddrives to 2 seagate 500Gig 7200.11 in Raid-O and upgrading my DVD player and DVD burner to Sata Drives. What do you guys think? Worth the upgrade?

Nope. I don't think your PC needs any upgrades this year.

If you need more room, by all means add more hard disks. If you don't, and you just want to replace the old disks, it makes no sense to me. The speed improvements between 7200.10 and 7200.11 are too small to make it worth while.

As for the burners, if you replace them with SATA versions, all you get is narrower cables and (hopefully) a small improvement in cooling, if the wide IDE cables were impeding airflow. Again, not worth it IMO.

If you've got money and really really want to spend it, maybe get yourself a nice monitor. What have you got now?

Definately not.

OK, here's a crazy idea. Add more disks and do a different kind of RAID, something with a safer behavior than RAID 0.

I have 2 19 inch wide screen monitors that have served me well. I was thinking about getting bigger ones, but im pretty happy with what i got.

I agree with both of aevm's posts. If you go RAID-5, you'll get to spend money on a RAID controller.

Keyboard? Rodent? UPS? Speakers? Headphones?

I think the P5B Deluxe can do RAID 5 already. Is it this one here?

The problem with the monitors is that you need to upgrade both together, to identical models. If you try to live with a 19" and a 22" side by side it stinks.

Yeah, maybe some speakers... Or some more games, one can never have enough games.

Mobo RAID-5 will be a lot slower than RAID-5 on a separate card, and a separate card will allow you to move the array to another PC later.

Ah, good to know.

OK, I'm out of ideas now. That PC is just too good.

The old saying "If it's not broken don't fix it!" comes to mind.

RAID-5 is a good idea but you need a hardware raid controller for it.
