Reviving old PCs with Linux now that new ones cost an arm and a leg

Apple sharply raising the prices of laptops and other gear brought home that the datacenter-driven computer parts shortage is only getting worse. It will be years before prices fall, with RAM at the epicenter of the crisis. The long-awaited Steam Box is $1049 to start, with disappointing specifications. The good news is your old PC is not dead: you just have to replace the bloated operating system on it with Linux.

Here is the thing: those machines are not slow because they are old. They are slow because Windows got heavier while the hardware stayed the same. Linux does not have that problem. A fresh Ubuntu install with Xfce uses roughly 650MB of RAM at idle. Windows 11 uses 3 to 4GB before you even open a browser. The math is not complicated. Three major releases in 2026 prove that lightweight Linux is not a niche interest. BunsenLabs Carbon shipped in February on Debian 13, though it dropped i386 support, which matters if you are working with truly ancient hardware. Xubuntu 26.04 LTS arrived in April with Xfce 4.20 and three years of support. Linux Lite 8.0 landed in June with custom performance kernels, a built-in gaming stack, and a local AI assistant. The ecosystem is active, and it wants your old machine.

Liam. S's "Complete Revival Guide" shows how to pick a distribution appropriate for your old hardware. The older it is, the pickier you must be (for example, my ancient polycarbonate iMac can't run 64-bit, so I'll be wanting one of these, and antiX is Liam S's recommendation) but recent machines can run Xubuntu or Mint just fine. And even with hardware prices soaring, you can likely find an affordable SATA SSD that'll make a huge difference to machines so old they still have spinning rust in them.

A typical old laptop with a mechanical drive boots Ubuntu in 45 to 60 seconds. The same machine with a SATA SSD boots in 12 to 18 seconds. Application launch times drop from 5 to 8 seconds down to under 2 seconds. The entire system feels like a different machine, and the upgrade usually costs less than 30 dollars for a 256GB SATA drive.

Of the many tips, here's one that's easy to forget: open it up and clean it out. Old laptops can be choked with dust, and old tower desktops may contain unspeakable horrors.
