16gb ram upgrade (2x8gb sticks) and a 1tb m.2 drive. Ran pretty well, but built myself a gaming pc as dont need to stick to a laptop no more. Used to play a lot of csgo, fortnite and minecraft on this when younger. Havent used it much in last couple years so happy to sell now. The thermal paste was replaced at somepoint but not sure what paste it was so up to you if you want to replace that with mx6 artic (ive used in my pc done a good job tbf)
