Most folks I know don't want to sit next to noisy heat-generating equipment in a lab, in the uncomfortable workspaces that often accompany them.
Keep only lab gear in the lab, with enough workspace for the just the physical hands-on type of work that's sometimes required.
Invest in switched remotely manageable power strips, remote KVM/Serial., and layer 1 switches (e.g. http://www.mrv.com/tap/physical-layer/ ). SSH/RDP access to the various lab hosts for things like packet capture, traffic generation, test automation, etc. Hire a cable-monkey (no offence intended to cable monkeys) to plug everything in. Document everything very very well.
Then, outside of the lab itself, set up some number of comfortable workspaces in a quiet setting, multiple monitors, etc., for the folks that actually need hands-on.
Let everyone else access it remotely.
