I know I'm late to the party...
1. It's nearly impossible to have 16TB worth of storage on a consumer desktop. Reasons include: 2TB partition limit, SATA power cable limits, SATA data port limit (not enough on mobo), and the largest drives out there are 1TB (1.5TB drives coming soon). There's physically no way they would fit in a case, then you have to find a way to power them/feed data.
2. There's no way that a Xeon can run at 5.8Ghz 24/7. Suicide runs, maybe, depends on the chip, but not 24/7
3. There's no such thing as a 9800GTX2
4. I thought the *awesome* PC was at your brothers work? Then you say it's just a *hub* that is in one of your houses rooms.
5. That's all. I'm off to class.
~Gooda~
