I'm planning to build a tower-only office PC with a budget of up to $1,200, purchasing every component from Amazon.com. It will mainly handle spreadsheets, accounting software, documents, PDFs, many browser tabs, and several applications open at once. Gaming is not a priority. I'd like 32GB of memory, at least a 1TB SSD, and possibly 2TB if the extra cost is reasonable. Either Intel or AMD is fine, but reliability, quiet operation, and long-term durability are more important than maximum performance. The computer may remain powered on for extended periods, and I'd prefer to spend less than $1,200 if these workloads do not require that much.

For this workload, an Intel Core i3-14100 is already fast enough, while an i5-14400 gives you extra headroom for heavier multitasking. A DDR4 platform can reduce the cost without making a noticeable difference in office applications. Spend the savings on a reputable TLC-based SSD rather than a cheaper QLC model, use a case with good airflow, and set the fans to run slowly for quieter operation.
For spreadsheets, documents, PDFs, and normal accounting software, it should remain adequate for quite a while. If you expect much heavier workloads or want more long-term breathing room, the i5-14400 is a reasonable upgrade, but a higher core count is not essential for typical office use.
You could spend considerably less than $1,200. A previous-generation AM4 system with a Ryzen 7 5700G, 32GB of DDR4, integrated graphics, and a 2TB SSD would still be more than capable for office work and should last for years. A 550W–750W quality power supply is plenty, and a simple case with a couple of quiet fans will keep temperatures and noise under control.
An AMD AM5 system would be a good fit because it offers integrated graphics, efficient performance, and a better upgrade path. Something like a Ryzen 5 7600G with 32GB of DDR5-5600 or DDR5-6000 should handle accounting software, multitasking, and plenty of browser tabs easily. That should also leave enough room in the budget for a 2TB NVMe SSD and a quality power supply.

Would the Core i3-14100 still be a good choice five or more years from now?
