We primarily sell CPUs, all of which are pulled from fully functional machines. We do not sell non-working units.Please note that CPUs may have residual grease, which is normal and may need a quick clean. The item pictured is for illustration purposes only, and the actual item you receive may vary slightly in appearance. If you have any questions, feel free to reach out to us. Grade A - Light cosmetic wear to no wear. Grade B - Medium wear Grade C - Heavy wear If the product title specifies a missing cap, a chipped corner, or other cosmetic imperfections, the CPU remains operational. We are also happy to review all bulk offers. In addition to CPUs, we also sell hard drives and RAM in bulk. Thank you for your interest, and we look forward to serving you!
