If you happen to have a troller full of old pc’s waiting in the office to be collected and further disposed, you can still utilize them. For example you can cheer up your collegues by carrying the old pc’s and place them onto your collegues room or a cubicle.
You should do this when your collegue is in a meeting. Do remember to connect all wires =)
Then ask your your collegues boss to wait until your collegue comes to his or hers room/cubicle and then the boss to instruct your collegue that any additional pc’s require a permit…
