If you can't sell them on here, PC enthusiast forums, reddit, etc... there are TONS of ways to donate (and get tax deductions). About 10 years ago, I couldn't really get enough for my back-up gaming PC or my wife's laptop to make it feel worth it, so I passed them on to an after-school music production program in North Philly.
Not a bad idea for the three laptops. I'd be pretty disinclined to do this with the desktop though, as I'd not be able to realize the deduction until 16 months from now. The timing is about as bad as possible to do a deduction with the year just having rolled over. If it doesn't sell at close to what I'd like to see, it's definitely another decent option that could possibly be a greater value. This machine is a massive overkill for any school usage though: https://pcpartpicker.com/list/QNCXhq
///Bearer of bad news.. Not trying to be a ****... But this is a tech forum, where most people are knowledgeable about this stuff..
The Am3 board and 9590 cpu are not in demand..
It's very unlikely anyone will pick up on this box in totality, because the price to performance ratio is very low due to the Amd platform. If they do, expect a steep discount...
If you do want to sell this,
--- At the very highest, you'll need someone who is relatively unaware of the current cpu landscape, And bad at math.. so,,, local craigslist is best for that type of audience..
--- In the middle, you can sell Everything OUTSIDE of the cpu / motherboard at 30-40% markdown.
--- At the Low end, you'd sell it in pieces at 40%-50% markdown...
The stuff you got outside of the cpu/motherboard is good mid-tier stuff. and would sell on their own, butttttt, IMHO there's no real point since they'll fit your next build just fine..
