It’s easy to a**ume a home server wouldn’t necessarily need a GPU. After all, most of the time it sits headless in a closet or rack. But when the day comes that you do need one, you’ll be glad you kept a cheap card plugged in. Over time, I’ve found that a cheap, even pre-owned GPU isn’t just a safety net. It can be a quiet workhorse that makes your entire setup more versatile.
