Montech KING 65 PRO (B) ATX Mid Tower PC Case

Dual-Chamber Mid-Tower Build

The Montech KING 65 PRO (B) is an ATX mid-tower case built around a dual-chamber layout that separates the power supply and drive cages from the main component area. Tool-free tempered glass panels and a spacious interior suit system builders who value quick assembly and easy future upgrades. Three pre-installed ARGB PWM fans provide immediate cooling and lighting without extra purchases.

Cooling Capacity and Limits

High-airflow mesh panels feed a flexible fan and radiator topology: the top accepts up to 360 mm or 280 mm radiators, the side supports 240 mm or 140 mm units, and the rear takes a 120 mm radiator. Fan mounts include bottom positions for two 140 mm or three 120 mm fans, top for two 140 mm or three 120 mm, rear for one 120 mm, and side for two 120 mm or two 140 mm fans. Graphics cards up to 420 mm long, CPU coolers up to 175 mm tall, and power supplies up to 190 mm deep fit comfortably; longer GPUs, taller coolers, or deeper PSUs will not install.

Upgrade Context

The case replaces older single-chamber enclosures that restrict airflow and cable routing behind the motherboard tray. Its dual-chamber design and 420 mm GPU clearance make the jump worthwhile when moving to modern high-wattage graphics cards such as RTX 40 Series models that demand generous length and strong front-to-rear airflow. Builders upgrading from cramped chassis gain seven expansion slots, support for five 2.5-inch SSDs or two 3.5-inch HDDs, and a cleaner internal layout without changing motherboard form factor.
