I've got two lots of 2x 8GB DDR4 non-registered UDIMMs for sale (32GB total). All 2400MHz with the same specs, pulled from an HP EliteDesk 800 G2 in great working condition.

$40 per module, or $130 for them all.

Located in Palmy but can easily arrange courier for an extra $10-15 depending where you're based.
