6 Best Alternatives to the ASUS NUC 15 Pro Mini (2026)

How these alternatives compare to the NUC 15 Pro

Lenovo ThinkCentre Tiny Core i5 Mini PC

The Lenovo ThinkCentre M70q uses a 14th Gen Core i5-14400T processor instead of the newer Core Ultra 5 225H. You get the same 32GB DDR5 RAM and 1TB SSD storage, but the graphics rely on integrated Intel UHD rather than the Arc 130T found in the NUC 15 Pro. This model is wider at 7.2 inches compared to the NUC’s 4.4-inch width, making it less compact. It supports WiFi 6, whereas the NUC offers faster WiFi 7 connectivity. The M70q lacks the dedicated NPU for AI acceleration, so it is better suited for standard business multitasking rather than local AI model inference. Choose this if you prioritize established business reliability over cutting-edge AI features.

Lenovo ThinkCentre Tiny 32GB RAM PC

This Lenovo ThinkCentre M70q Tiny model features an older 12th Gen Core i5-12500T processor, which is less powerful than the NUC 15 Pro’s Core Ultra 5 225H. It still includes 32GB of RAM and a 1TB SSD, providing ample memory for office work. The graphics are integrated and do not match the performance of the NUC’s Arc 130T GPU. Like the other M70q variant, it uses WiFi 6 instead of the newer WiFi 7 standard. This unit is designed for dual-monitor setups and general productivity. It lacks the advanced cooling and tool-free upgradeability of the NUC 15 Pro. Select this option if you need a budget-friendly, stable system for daily office tasks and do not require high-end graphics or AI processing capabilities.

ASUS NUC 14 Pro Tall Mini PC

The ASUS NUC 14 Pro Tall Mini PC shares the same 32GB RAM and 1TB SSD configuration as the NUC 15 Pro. However, it uses an older generation processor and lacks the Core Ultra architecture. The chassis dimensions are nearly identical, measuring 4.41 inches in width and 2.13 inches in height. This model is marketed as a premium option for users who value upgradeability. It does not include the NPU for AI acceleration found in the NUC 15 Pro. The connectivity options are robust but may not include the latest WiFi 7 standard. Choose this alternative if you prefer a slightly different form factor or need specific legacy compatibility. It is a solid choice for professionals who need high-speed connectivity but do not require the newest AI-focused hardware.
