There are few better feelings than cracking open fresh boxes of PC hardware. Remove the peel from your case side panel, unearth your shiny new GPU from its soft-shell foam packaging, and enjoy that new-RAM smell. There’s nothing wrong with buying brand-new parts, and I enjoy that experience as much as the next PC enthusiast, but buying used hardware to save a buck will always be more alluring. I always look for these 4 components on the used market before I even think about buying new.
