SilverStone Precision PS15 is all about the money and a low price that comes in under £40. The Precision Series of ‘High-value tower chassis’ covers the range from microATX through ATX to Full Tower ATX, however each model is quite distinct from the others with no obvious connection between, say, the PS13, PS14 and PS15. This meant we had very little idea what to expect as we unboxed the PS15 and truth be told, we were very happy with our first impressions. It is a smart and under-stated case with a full tinted glass window and a front panel that is mesh from top to bottom. It was crystal clear from the first moment that PS15 was designed to breathe.
