Best Refurbished Desktops Under $300 in 2026

A refurbished desktop is the most cost-efficient computer you can buy. For $150–$300, you get a business-class machine built to last — far more power than any new computer at that price point. Our technicians in Reno, NV have tested these units under real workloads. Here are the three that deliver the most value under $300.

Quick Answer

The Dell OptiPlex 3070 ($209.30) is the best overall refurbished desktop under $300. For the smallest footprint, choose the HP EliteDesk 800 G5 Mini ($249) with its 8-core i7. On the tightest budget, the Lenovo ThinkCentre M720q ($179) is a workhorse that runs Windows 11 and handles everyday computing without issues.

Why Buy a Refurbished Desktop Instead of a New One?

New desktops under $300 are almost universally underpowered — Celeron or Pentium CPUs, 4GB RAM, slow eMMC storage, and no upgrade path. A refurbished business desktop in the same price range gives you Intel Core i5/i7, 16GB RAM, NVMe SSD, and standard components you can swap, upgrade, or repurpose for years.

Frequently Asked Questions

What is the best refurbished desktop computer under $300?

The Dell OptiPlex 3070 at $209.30 is the best refurbished desktop under $300 for most users. It has an Intel Core i5-9500 (9th gen), 16GB RAM, 256GB SSD, and runs Windows 11 Pro. It is reliable, easy to upgrade, and uses standard ATX parts for future expansion.

Are refurbished desktops reliable?

Business-class refurbished desktops from Dell, HP, and Lenovo are extremely reliable. They were built for multi-year enterprise deployment, use server-grade components, and are tested to MIL-SPEC standards. At Online Used Laptops, every desktop passes a 15-point inspection including stress tests, memory diagnostics, and storage health checks before shipping.

Can a refurbished desktop run Windows 11?

Yes. All refurbished desktops at Online Used Laptops with 8th gen or newer Intel processors ship with Windows 11 Pro pre-installed and activated. The Dell OptiPlex 3070, HP EliteDesk 800 G5, and Lenovo ThinkCentre M720q all support Windows 11 natively.

What is the difference between a mini PC and a tower desktop?

Mini PCs (like the Dell OptiPlex 3070 Micro or Lenovo ThinkCentre M720q Tiny) are palm-sized and mount behind a monitor. They use the same laptop-class CPUs and are more power-efficient. Tower desktops use full-size desktop CPUs, have more expansion slots, and are easier to upgrade with standard components. For most home/office users, a mini PC is plenty.

Can I add more RAM or storage to a refurbished desktop?

Yes — this is one of the best reasons to buy a refurbished desktop over a laptop. The Dell OptiPlex 3070 and HP EliteDesk 800 G5 both have open RAM slots (upgradeable to 32GB or 64GB) and free 2.5" SATA bays for adding more storage. Standard desktop RAM and drives are inexpensive.

Do refurbished desktops come with a monitor?

The desktops listed here are sold without a monitor, keyboard, or mouse — the core unit only. We also carry refurbished monitors separately. A 24" 1080p refurbished Dell or HP IPS monitor runs $80–$120 and pairs well with any of these units.
