Prime Day 2021 has proven itself to be a great time to buy a new set of headphones, a new TV, a phone, and lots of other things. It’s also a stellar opportunity for PC builders to score discounts on memory, storage, power supplies, desktop cases, monitors, processors, and more. The only things you won’t find discounts on (in 2021, at least) are graphics cards, which are still very much in demand and hard to find.

Whether you’re building an all-new PC piece by piece (for gaming or general use), upgrading one or two parts this year, or hoping to grab some discounted accessories, we’ve got a few categories below containing the best deals we’ve found.
