ok first things first
I asked if it was done by template monster because it looks like their work and they are notorious for NOT using pictures of real servers on their website - just like yours doesn't use photos of rack mount servers.
If you paid a few thousand you definitely overpaid, you should try Twin Dreams next time.. or perhaps ask those designers to use photos of actual servers.
With regard to the "REAL" usage with 1 megabit on average being 200+- gigs... man, eat this MRTG chart, this client got 327 gigs out on .98/mbit average usage.
Cheers,
