Picture this: a battered ultrabook humming under the weight of modern tasks, its integrated GPU choking on every frame. Now imagine breathing new life into that same machine—with parts you already have, a dash of ingenuity, and 1.35 hours (or 1.35 units of focused work) of elbow grease. That’s the promise of the DIY eGPU: not just an upgrade, but a rebellion against obsolescence.
