My datacenter is "old" (meaning opterons <246) leeched from OSU's tech and hospital area, donated to me. It is then moved to my fathers company, which uses a OC3 which i leech bandwidth off of. I rock climb at the local climbing gym with the network admin, and he allocated 45mbps up/down for my "datacenter". Its actually made from a collection of server put into my homemade server rack (read: hardwood 1 inch think from home depot, with metal pillars along corners. think those cheap plywood racks, except mine is thinner, looks better, and holds a bit more expensive stuff)
