About computers & laptops scrap
A desktop is really several materials in one box: a steel or aluminium chassis, a power supply with copper windings, a motherboard and add-in cards, drives, and cabling. We assess these together, but the board grade is what usually decides the value. Servers and workstations sit above ordinary desktops for exactly that reason.
Working equipment is a separate conversation. If a machine still has working life, refurbishment is worth more than recycling, and we will say so rather than buying a functional unit at scrap weight. That is particularly true of recent laptops.
For office disposal the process matters as much as the price: an itemised list of assets, drive wiping or physical destruction, a signed handover, and routing to an authorised e-waste recycler so your disposal record stands up to audit. CRT monitors are handled separately, as they need controlled processing.
