The Corsair 3500X RS-R ARGB is a mid-tower case with removable tempered glass on the front and side, and it sits at number four in this guide. It takes motherboards from Mini-ITX up to Extended ATX and arrives with three RS120-R ARGB fans already fitted, controlled from a +5V ARGB header on the board. The clearest number in its listing is not the fan count but the price: this version is £74.99, while the same 3500X chassis is listed at £61.27 without fans. Thirteen pounds and change is what three RS120-R ARGB fans cost here — which is why the fan figure on a case advert is a capacity figure, not a contents list.

That matters because this listing carries two different 10s. The bullets describe side, roof and PSU mounting points for up to 10x 120mm fans; the specification table then gives an "Internal Bays Quantity" of 10, a figure the advert never explains, on a case whose storage drives are not what the bullets are counting. The title promises three fans in the box. Everything on this page comes from the Amazon listing for this model, not from our own testing.
