Outfitting a new datacenter?

We completed our new 4,000 sq ft data center (Tier II/III, according to The Uptime Institute) and just recently moved our core systems from our old data center to the new. We've been up and running for several months now and I'm preparing to close out the project. The last piece is to purchase some accessories and tools for the new location.

The short list so far consists of a Server Lift, a few extra floor tile pullers, flashlights and a crash cart. We'll also add to the tools in the toolbox located in one of the auxiliary rooms - these things seem to have legs! What are we missing? Where can we find crash carts set up more for a data center environment (beyond the utility cart with and LCD, keyboard and mouse strapped to it)?
