The Datacenter of your Dreams

Tell me that your secret CIO fantasy isn't to "appropriate" some of those funds painstakingly carved into your budget for replacement mice and build yourself one of these instead: a super-secure underground datacenter in a former nuclear bomb shelter buried beneath the bedrock of Stockholm.
I've always liked indoor waterfalls. Still, is that really the smartest thing (with the associated fog and jungle plants, which makes the whole thing look a bit like the Wailing Caverns to me) in an underground bunker complex packed with electronic equipment? But fantasy datacenters have never had much to do with reality, I suppose.
