What affordable DDR4 processor and motherboard would work for a basic office PC?

My dad's laptop recently died, and we're trying to replace it without spending a lot on DDR5 memory or unnecessary performance. The computer would only be used for word processing, spreadsheets, web browsing, and similar office tasks—no gaming or demanding video work. I'd prefer a processor with integrated graphics so a dedicated GPU isn't needed. I'm open to either AMD or Intel, but I'd like a reliable, hassle-free setup that won't require a BIOS update before it works. Would building with an older CPU and motherboard make sense, or would a used office PC or mini PC be the better choice?

If you want to build, Intel’s 8th-generation Core processors and newer models with integrated graphics are more than powerful enough. A 12th- or 13th-generation Intel system using DDR4 would give you more performance and longevity, but make sure the specific motherboard and CPU combination is already supported. Since you don’t want to deal with BIOS updates, buying a board and processor as a matched, compatible package is important.

A used laptop or business mini PC may offer much better value than a new DIY build, especially if the total budget is around a few hundred dollars. A refurbished ThinkPad, small office desktop, or reputable mini PC with 16GB of memory and a 512GB SSD should feel fast for office work. Since the old laptop was effectively used as a stationary computer, portability may not matter much, but a laptop remains an option if that changes.

Older AMD AM4 systems can work well, but check the graphics support carefully. Many Ryzen chips, including the Ryzen 5 3600 and 3600X, do not have integrated graphics, so they would need a separate video card. An AMD APU or an Intel chip with built-in graphics would be a better fit for a simple office machine.

For this use case, I’d strongly consider a refurbished business desktop or mini PC instead of building from individual parts. Dell OptiPlex, HP EliteDesk, and Lenovo Tiny systems are quiet, efficient, inexpensive, and usually include Windows. An 8th-generation Intel system or newer with 16GB of RAM and a SSD should handle Office and browsing comfortably, while also meeting the requirements for newer Windows versions.

The exact budget matters, but building new probably isn’t the best way to minimize cost here. Even a modest system needs memory, storage, a case, a power supply, and an operating system. A second-hand or refurbished business computer is usually cheaper, easier to set up, and already tested. I’d prioritize 16GB of RAM, an SSD, integrated graphics, and a reputable seller over getting a particular high-end processor.
