Thermaltake S100 Price & Colors
No new listings for the Thermaltake S100 today - specs, fit and used options below. A mATX case that fits GPUs up to 350mm.
Our verdict
The S100 is a quiet little micro-ATX box with a clean look and a solid-panel front that inevitably runs warmer than mesh rivals. For modest hardware in a bedroom or office it is tidy and cheap; for hot parts it is the wrong shape.
Best for: Modest builds - midrange GPU and down - that value clean looks and low cost.
Skip it if: Your GPU pulls 250W+ - the solid front chokes exactly when you need it not to.
Not stocked new right now
Cases rotate in and out of stock constantly, and this one may well be back. Nothing about the case has changed - the specs below still decide whether your parts fit, and a used unit is a safer second-hand buy than most components since there is nothing inside it to wear out.
