[vcf-midatlantic] Exposed pins on vintage computers in storage

I have a system in climate controlled storage. I currently leave all the CPU and memory boards installed. It has large connectors that are male pins on side of computer and female on side of the CPU and memory boards. Would it be a big deal to leave the boards removed from the system? The boards weigh a lot and I plan to move it upstairs in the storage unit -- reset the rent counter and lower the size of the unit. I could potentially get some desicant and wrap up the boards if needed but the cabinet not so much (it's a Cray.) Any thoughts? - Ethan
