Where can I buy a used pc?

You can buy a reliable used PC from reputable refurbished computer retailers—both online and in-store. At System Liquidation, all of our devices are technically “used,” but they are professionally refurbished, meaning they’ve been restored to manufacturer-level performance and quality standards. This ensures you get far more reliability than you would from a typical secondhand marketplace.As a Microsoft Authorized Refurbisher and trusted partner of Dell, Lenovo, HP, Acer, and Google for Education, we follow rigorous testing and quality-control processes to deliver refurbished desktop PCs, refurbished HP laptops, Dell refurbished computers, and more—all backed by a 1-Year Warranty and Free U.S. Shipping.

What are the best brands for refurbished desktop computers?

For dependable refurbished desktops, most IT teams favor enterprise lines with strong parts availability and long lifecycle support. Top picks include the Dell OptiPlex (3000/5000/7000 series) for broad configurations and easy serviceability; HP EliteDesk and ProDesk for stable, business‑class builds; and Lenovo ThinkCentres M‑series for reliability, compact sizes, and robust manageability. For heavier workloads, CAD, analysis, creative, consider workstations like Dell Precision, HP Z‑series, or Lenovo ThinkStation, which add higher‑tier CPUs, ECC options, and professional GPUs.

Are refurbished desktop computers good for business or school?

Yes. Refurbished desktops are a cost‑effective, reliable choice for offices, classrooms, labs, and home workstations. System Liquidation’s inventory of refurbished computers are professionally cleaned, repaired, data‑wiped, and hardware‑tested before shipping with a fresh OS. Product pages list cosmetic grade, exact specs, and warranty, so you can standardize across a fleet with confidence. Business and education buyers often select Dell OptiPlex, HP Elite/Pro, and Lenovo ThinkCentre for stability, driver support, and easy service.

What’s the difference between refurbished and brand‑new desktops?

Brand‑new desktops arrive factory‑sealed with full OEM warranty and original accessories. Refurbished desktops are previously owned, leased, or open‑box units restored to full functionality. During refurbishment, systems are cleaned, data‑sanitized, inspected, restored, and tested; components like storage, memory, fans, or power supplies may be replaced if needed. A fresh, activated operating system is installed, and the cosmetic grade is disclosed. Refurbs typically include a limited refurbisher warranty and deliver significant savings versus new, letting organizations stretch budgets or step up specs (more RAM/SSD) for the same spend. Choose brand-new if you require specific OEM programs, very long warranty terms, or the latest platforms; choose refurbished desktops from System Liquidation for value, sustainability, and rapid deployment. Either way, you can request bulk quotes, standardized builds, and documentation for asset management, with free shipping available across the U.S.

What specs should I choose for a desktop PC?

Start with workload. For office and web apps, a recent Intel Core i5 (10th–13th gen), 16GB RAM, and a 256–512GB NVMe SSD deliver a fast, quiet experience. For multitasking, light photo/video work, or coding, step up to a Core i7 and 32GB RAM. If you run CAD, analysis, or creative suites, consider a workstation with higher‑core CPUs, more RAM headroom (32–64GB), and dedicated graphics (NVIDIA or AMD).Storage strategy matters: pair a fast NVMe boot drive with a larger SATA SSD/HDD for files. Connectivity: ensure DisplayPort/HDMI for dual monitors, plenty of USB‑A/USB‑C, Ethernet, and optional Wi‑Fi if you’re not wiring. Security and manageability: look for TPM, BIOS/UEFI controls, and vPro/AMT where required. Small‑form‑factor or micro desktops save space; towers offer best expandability. System Liquidation’s listings detail CPU generation, RAM slots, drive bays, power supply, and warranty.

Do refurbished desktops include a warranty and support?

Yes. Each refurbished desktop from System Liquidation’s comes with a 1-year limited warranty support beginning on the original purchase date. The 1-year limited warranty covers any and all product defects (labor, hardware and software). An additional 1-year warranty is also available for purchase as an add-on.

Can I add Wi‑Fi, Bluetooth, or a graphics card to a refurbished desktop?

In most cases, yes. Many business‑class desktops support upgrades like PCIe graphics cards, additional RAM, and extra storage. If the system doesn’t include Wi‑Fi/Bluetooth out of the box, you can select it as an add-on on the product page.Small‑form‑factor and micro models have tighter space and power limits, so check the listing for power supply wattage, available PCIe slots, and low‑profile GPU compatibility. Towers offer the most flexibility for full‑height GPUs and multiple drives. System Liquidation’s product pages outline form factor, expansion options, and included ports (DisplayPort/HDMI, USB‑C, USB‑A, Ethernet). Ask sales to preconfigure RAM/SSD upgrades, confirm GPU fit, or bundle accessories like Wi‑Fi adapters, keyboards, mice, and monitors. For classrooms and offices, they can also standardize images and BIOS settings across your deployed fleet.

How do small‑form‑factor (SFF) and micro desktops compare to towers?

All three can deliver excellent performance, but they trade space for expandability. SFF and micro desktops are compact, energy‑efficient, and perfect for classrooms, call centers, reception areas, and tight desks—often supporting dual displays with very low noise. They’re ideal for web, office apps, and light creative work, and they simplify cable management and mounting behind monitors.Towers are larger and better for upgrades: more RAM slots, drive bays, and full‑height GPUs for CAD, 3D, and media workflows. Refurbished lines like Dell OptiPlex, HP Elite/Pro, and Lenovo ThinkCentre come in multiple sizes, so you can match footprint to workload. When browsing System Liquidation, use filters for form factor, CPU generation, storage, and memory. If you’re planning a mixed environment, our sales staff can help standardize images and peripherals while right‑sizing power supplies and cooling to your applications.

How fast is shipping, and do you support bulk orders?

Most in-stock items at System Liquidation are processed within 2–3 business days, though some orders may take 4–5 business days or longer if backordered. Shipping times vary by carrier, with standard UPS deliveries during the holidays typically arriving within 2–5 business days after leaving our warehouse.Please note that shipping cutoff times vary, and next-day shipping is not guaranteed.Weekend Closure: Orders placed from Friday 6:00 PM to Sunday 11:59 PM EST are processed the next business day. We also do not process orders on weekends or major U.S. holidays. Seasonal volume and weather may cause additional delays.Yes, we fully support bulk and enterprise orders. We offer volume pricing, standardized configurations, OS imaging, asset tagging, bundled peripherals, and coordinated multi-location or staggered shipments.

Do refurbished desktops come with monitors?

Refurbished desktops don't come with a monitor included, but there is an option to add an LCD monitor to your order at an extra cost. If you are looking for desktop and monitor combos, browse our refurbished bundle collection.If you prefer to select your own refurbished display, we offer a wide selection of refurbished Dell and HP monitors, all professionally cleaned, tested, and verified for full functionality. Additionally, refurbished All-In-One (AIO) computers always come with a built-in display, making them a great space-saving solution for classrooms, front-desk areas, and compact workspaces.
