Customer's laptop screen was physically damaged. He did not want to buy a new laptop - this one worked just fine. Even at five years old, the replacement LCD screen part was still available - and once received was installed in under an hour.

A five year old Asus desktop PC. Customer only needed something for basic web browsing and emails. No need for a new PC. Upgraded RAM to 8GB, replace the old hard drive with a faster Solid State Drive (SSD). Cleared the boot process of unnecessary junk. Result: boot time cut ~2.5 minutes to just 35 seconds.

Things you may already have: old computer (laptop or desktop) collecting dust. Old mobile phone. Add a windows/suction phone holder and free apps. All together = a simple yet effective CCTV system. Use motion control to record only when needed. Can even save to the cloud for extra security.
