Specs compared

How we chose these

We reviewed the three Oemgenuine desktop listings that matched our pool: all were Lenovo ThinkCentre models aimed at business and office use. We shortlisted based on processor, memory, storage, operating system, and form factor, excluding any that lacked a clear specification. Prices are live and read from the store listing at the time of writing; we have not tested any of these units. Our recommendations rely on the sellers' stated specifications and on manufacturer information for Windows 11 requirements and processor features.

What to look for

Processor: what to look for

The processor is the heart of a business desktop. All three Oemgenuine picks have 16GB of RAM and Windows 11 Pro, but they differ in CPU. The Intel Core Ultra 3 205T in the M70q is part of Intel's Core Ultra series, which includes an NPU for AI acceleration on select models, according to Intel. The AMD Ryzen 7 250 in the 55s is a higher-tier part in the Ryzen lineup, though we don't have independent performance data. If the CPU is not stated, as with the Tiny M70q, treat it as an unknown and verify with the seller before buying.

RAM and storage

Every desktop here comes with 16GB of DDR5 RAM, which comfortably exceeds the 4GB minimum required for Windows 11, per Microsoft. Storage ranges from 256GB to 512GB. For typical office files, 256GB may suffice, but if you handle large media or software packages, 512GB gives more headroom. Consider whether the storage is expandable, though this isn't stated in the listings.

Operating system: Windows 11 Pro vs Home

All three desktops ship with Windows 11 Pro, which is designed for small business and enterprise environments. It includes features like BitLocker device encryption, domain join, and remote desktop, which are not present in Windows 11 Home. Microsoft's comparison shows these Pro-specific features are aimed at productivity and security. If your workplace requires these, Pro is the right choice.

Form factor and expansion

These desktops come in two shapes: tiny (ThinkCentre M70q and Tiny M70q) and small-form-factor (ThinkCentre 55s SFF). Tinies are ideal for cramped desks and can be mounted behind a monitor, but may have fewer expansion slots. The SFF offers a bit more room for internal upgrades, though specific slot counts are not listed. For most office tasks, the compact footprint won't limit performance.

Connectivity and wireless

If you want to avoid cable clutter, look for Wi-Fi and Bluetooth. Only the M70q Gen 6 lists Wi-Fi 6E and Bluetooth; the other two don't mention wireless at all, so you may need to use Ethernet or add a USB adapter. Check the listing's full specifications for available ports, as they are not all detailed in the summary.

Questions

Are these Oemgenuine desktops suitable for gaming?

These are business-focused desktops with integrated graphics only. None of the listings mention a discrete GPU. They can handle basic games and productivity tasks, but they are not designed for modern gaming at high settings.

Can I upgrade the RAM or storage later?

The listings do not state whether RAM or storage is expandable. Typically, ThinkCentre tiny and SFF models have some upgrade capability, but it varies by model. Contact the seller or check Lenovo's documentation for specific instructions before purchasing.

Do these desktops come with a keyboard and mouse?

The product names and specifications do not mention any included peripherals. Plan to purchase a separate keyboard and mouse if you don't have them.

What is the warranty on these machines?

Warranty information is not provided in the catalog. Check the product listing for warranty details or contact the seller directly.

Can these run Windows 11 Pro even though they have 16GB RAM?

Yes, 16GB is well above the 4GB minimum for Windows 11, and the operating system is preinstalled on all three units, so they are ready to use out of the box.
