Why do you want full liquid cooling?
Liquid cooling is a complete waste of money.
Put that money into another video card or two.
Reasons to have liquid cooling:
1. Show off to your gaming friends how much money you have
2. You overclock like crazy (4.5 Ghz and up)
But back to your question about Digital Storm. They seem better than iBuyPower. They have a better variety of components you can chose from.
I am choosing to them oc my computer to 5.0 Ghz and have triple vids, and like you said to show off, but before I buy one is there another place I should check out, and do not say Alienware. I need your input
