This thread is very interesting.
Im on my way to upgrade my internet connection at 1Gbps and planning to buy another 1Gbps. The real problem is server costs since an intel xeon E5620 with 8GB, 600GB hdd is aprox 4000$.
Another option reasonable at costs may be buying two I7 desktops with 64 gb ram,2x2 T sata3 which cost around 1000$ second-hand each and using them as homemade servers for a tube where to host videos.
