What about it? We're talking small businesses here, this will not be a warehouse full of racks worth of machines to try and sell. We're likely talking 3 to 10 PC-sized machines in a closet or storage room. You can sell those on 2nd hand market pretty quickly and even if you sell them at 30-40% loss you are extremely likely to have already paid off the other 60-70% during the machines' service time.
You never know. While working in an ITAM role, I've had a manager point out a line item asking why we need 30 DisplayPort cables. This was in an org with multiple sites, 2000+ employees, using dual monitor setups both in house and remote. Whether physically, or in the cloud, companies whose primary business isn't tech-related see the IT side as an annoying cost center rather than a cost of doing business in the 21st century.
