First 1gig port speed is going to cost you in the thousands per month. Second 1TB is quite a bit make sure you need it all. If your sites videos ect. compress your videos. Theplanet.com is your best bet when it comes to network ect.
Well my friend has a 1GBIT connection line, , we were planning on setting up a few dedicated servers, but the only problem is, is it worth spending 350+ on a top spec system ?
