In my case, I have three servers (each with ECC 32GB, Xenon quad core, 2x3TB disks and unlimited bandwidth), a 5 port internal switch, two public IPv4 addresses per server, a public failover IP, 300GB of network backup space and two additional rack slots reserved in the same rack for future expansion. The total monthly cost for this (exc. VAT) is €180. I haven't been able to find any co-location or cloud providers that can come anywhere close to that price for a similar resource setup.
