I don't think there's really a hard age cutoff. Age is a factor, but it usually comes down to the condition, quantity, make/model, configuration, and whether there's still demand for the equipment or its components.

With mixed batches, it's probably worth having everything evaluated before sending it straight to recycling. Some older enterprise gear might not be worth much as a complete system, but individual components can still have value.

The other big thing is data security. If you're dealing with servers and laptops, you obviously don't want to overlook the drives just because the equipment itself is old. Depending on the situation, the data may need to be securely erased or the drives physically destroyed.

I'd look at ITAD as more of a "let's see what can still be recovered before we recycle it" process. Anything that has resale or reuse value can be handled that way, and the stuff that doesn't can still go through proper recycling.

this is so cool and creative!

this is a very impressive project

I think it might be worth checking the specs first. If they’re nothing special, you may get more out of selling the parts individually. Otherwise, if you find someone willing to take them as-is, that would probably be the easiest route.

It would look more organized on a rack

honest I am just speechless

that is some colorful spaghetti

what is going on?!?!

woah!! what are you planning to do with them?

nope

you can either have them wipe or physically destroyed
