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 if possible, but DDR3 works too)
Hard drives or SSDs
Graphics cards
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!
