Basically, make a “business argument” for the upgrades. CEO’s are generally business bros with limited practical experience. They understand sales and people pleasing/kiss assing. So the right argument is usually how it will increase sales and make their employees more productive and happier.
Unfortunately with the current equipment being 7 years old, “anything is better than the shit we currently have”. With win10 being put to pasture, your company needs to do a full replacement. So buy the cheaper ones that the CEO wants, then work on convincing him to buy the higher end ones when the cheap shit dies in the next 2-4 years.
Phrase it like "Due to the urgency of our upgrade needs and budgetary constraints, I understand why we need to buy lower quality equipment. This equipment has a life expectancy of 2-4 years. I recommend when these lower quality models need replacement we go with a higher quality model and a life expectancy of 5-7 years. This will in the long term reduce our expected cost by $xxxx/year.
