There is recurring costs as well, something like $400/mo in power usage bills, and another $400 in internet and space rental fees per month. The folks over at the datacenter have been very happy to have me so there might be some discounts in there as well, but I am not sure. My goal was to keep the recurring cost as low as I can, and compared to what hosting a beast like this in a conventional datacenter would cost I'd like to think it's a pretty good deal.
Given that it generates like 10k BTU/hr or something like that the drain on the datacenter is non-trivial, so I a running cost was to be expected.
As somebody who started out in the 80s with Apple II and C64 stuff the year before going to college, I always laughed at the old “Star Trek’ episode where the new computer has to tap into the main engine for power. After seeing your new bit of kit, that doesn’t sound so far fetched :-)
