Can you build a gaming beast out of a 1-liter office PC?
In this video, I take a $100 Lenovo ThinkCentre M920q and turn it into the most upgradeable mini PC in the world. From Pentium to i7-9700, from 8 GB RAM to 32 GB, and from no GPU to a full-size RTX 4060 — all packed into a tiny footprint.
We test undervolting, liquid metal, delidding the CPU, cooling mods, riser cables, and even dual power supplies — all to push this SFF PC to the absolute limit.
Is it practical? Not really. Is it fun and insane? Definitely.

Specs after upgrade:
• Intel Core i5-8500/i7-9700
• 32GB DDR4
• RTX 4060 with undervolt
• Flex ATX 500W PSU
• Copper VRM heatsinks
• Liquid metal cooling

⚡ Total build cost: $545
💥 Final volume: ~2.7 liters
