Rosewill Helium Flow White Mid Tower PC Case

White mid-tower for ATX builds

The Rosewill Helium Flow White is an ATX mid-tower case built for standard desktop builds. It accepts ATX, Micro-ATX and ITX motherboards and ships in a white steel-and-plastic finish. A mesh side panel and additional mesh sections give the interior direct access to fresh air. The chassis is aimed at builders who want straightforward cooling without exotic layouts.

Tool-free panels and mesh upkeep

Side panels lift off without tools, so hardware swaps take seconds. The 1 mm mesh holes resist dust while passing high airflow; filters are fitted behind the mesh and can be rinsed clean. A 28 mm cable-routing channel behind the motherboard tray keeps wiring tidy. The only common snag is routing thick 12VHPWR cables through the 40 mm side-panel gap — plan the bend radius before you seat the GPU.

Drive bays, radiators and length limits

Three internal 3.5 inch bays and three 2.5 inch bays handle a typical storage mix. The front fits three 120 mm or three 140 mm fans; the top takes three 120 mm or two 140 mm fans; the motherboard zone adds three 120 mm positions; the rear comes with one 120 mm PWM fan pre-installed. Radiator support reaches 360 mm at the top and motherboard area, 120 mm at the rear. Graphics cards up to 390 mm clear the side panel, CPU coolers up to 165 mm fit under the mesh, and power supplies up to 240 mm long mount at the bottom.
