Once upon a time the outdated computer area was a source of spare parts, items of value when donated, or civic pride when given to charities, but in the rapidly changing world of technology yesterday's resources have become today's liabilities.  Some facts of today's realities:

Hazardous waste requirements limit the willingness of many recyclers to accept used equipment.  The costs of disposal are becoming an increasingly significant part of the cost of the technology.

Charities are finding that their ability to use older equipment is limited, and they too are faced with the task and costs of disposing of the donated equipment.  As a result, the legions of agencies willing to accept equipment have all but disappeared, and those who will accept it are careful to screen the less desirable.

The value of donations of used equipment for tax purposes has been lowered with changes in the tax code for depreciation.  As a result the ability to achieve tax savings has been significantly reduced.

The rate of depreciation of old equipment is accelerating, or to put it another way, machines are losing their value more rapidly. The longer you hold equipment the less value it retains.

The cost of that storage space being occupied by the walls of old equipment is becoming more expensive as tax, heat, and other costs increase the square foot costs.

In a nutshell, there are fewer and fewer places to take equipment of less and less value from spaces which cost the owner more and more money.
