GMKtec - NucBox M6 vs Lenovo - ThinkCentre M90q Gen 5

These two are nearly even on the Mars Score (67.1 vs 66.4). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the NucBox M6 if you care most about tdp and volume. The biggest gaps in its favor are tdp, volume.

Pick the ThinkCentre M90q Gen 5 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are ram, storage, thunderbolt.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
