This is my lab/workspace.
Not all systems are in continuous use, but they are available when needed. Several laptops and tablets are available for offsite use. The main server (there’s a picture showing it on a separate shelf on the wall – you’re using it now: this WordPress site runs on it), NAS, and other miscellaneous equipment is powered 24/7. Those that run continuously are powered by appropriately-sized UPS to permit them to run long enough to complete a controlled shutdown to prevent loss of data.
