The Thermaltake CA-1Y4-00SFWN-00 The Tower 300 Hydrangea Blue Micro Tower Chassis is a Micro Tower case for Micro ATX and Mini ITX motherboards. It takes graphics cards up to 280.0 mm long and CPU coolers up to 210.0 mm tall, and it has three 3mm tempered glass panels and two pre-installed 140 mm CT140 exhaust fans.

Compatibility and related parts
Check that your motherboard is Micro ATX or Mini ITX, your graphics card is no longer than 280.0 mm and any air cooler is no taller than 210.0 mm. For liquid cooling, the right-side mount takes a single AIO radiator from 120mm up to 420mm. The case uses a standard PS2 power supply, sold separately, so pick one from our power supplies, and browse CPU coolers or case fans to finish the cooling. Our PC builder checks compatibility, and assembly and testing are free when you buy the case as part of a PC build.
