Voodoo is WAY too expensive. Falcon is probably the way to go if you want to have a machine built for you in this way, but personally I think you should find out which parts to buy here and then go pay your local mom and pop computer store to build the machine for you for less than $100. You'll save thousands.
Why?? Take a look at a place like www.xicomputer.com. Slightly better system than a Falcon from Xi costs $1000 less!! This is not a little bit of money, you're paying for a bullsh!t name! Hell, go buy a Dell, it'll be cheaper.
