More likely a server was nicked.
Most people with access to data centers know that uplugging a random device or tampering with live kit might set off alarms or be caught on CCTV. I suspect some opportunistic contractor maybe spotted a small expensive (1U server) computer that he/she could nick and either flog for spares or use as a desktop at home.
Its likely this server was already -de-racked for some project and stored in a cupboard giving the contractor the unobserved opportunity for this heist, hence why RSA believe that it wasn't nicked for the data.
I once heard a story that during a previous server heist the thief actually went to the trouble of removing the server's hard drives and leaving them behind and thus reducing the urgency for the company to trace the thieves. - Not sure if this is an urban legend
