Planning for upgrade - need new case?

I want to upgrade my computer soon... and start building off of my "dream machine" specs on my ****-quality website that you can find here. I have a Tornado 1000 case already which has 5 fans on the outside. I don't know the sizes, but I want to say 80mm? They are just stock fans I got from the 3dcool.com website (which has now changed the way they do the Tornado 1000 - you now get like 2 stock fans and must order the others at an extra cost...). Would I be better off sticking with my Tornado1000 case, or getting new fans for it, or getting a new case completely (I don't care about glowing lights and crap). I will be using it to OC my Barton 2500 CPU... once I get it :)

Thanks for help :-D!!!!

I use an Antec 1000SX server case with a side fan panel and 5 Panaflo fans VERY Nice. I use a Nexus fan controller.

Actually gkline, your sig was the one I was looking at alot to review hardware online. I liked some of the hardware you have on your rig - and the fact you OC'd your Barton w/ the system you have now :-D Where is a link to see these panaflo fans, and do you think they'd be compatible if I swapped them into my current case?

I bought them at www. heatsinkfactory.com. Excellent overall prices. Everything else I bought at Newegg.com.

I bought the OEM Antec case at http://www.pcuniverse.com. I already had my Antec Truepower.
