Modern PC parts (passaic park)

Hello! I'm looking for any computer parts that are less than seven years old and in working condition. Specifically, I'm interested in components like:

CPUs (preferably i5 or i7 or equivalent, but open to others)
RAM (DDR4/5 if possible, but DDR3 works too)
Hard drives or SSDs
Graphics cards/gpu
Motherboards
Power supplies
If you have any parts lying around that you no longer need, I'd love to give them a new purpose!

Thank you in advance!
