PC Case Thermaltake CTE E660 MX Midi Tower Black

The CTE E660 MX is a PC chassis designed for the CTE form factor by Thermaltake, compatible with standard and Hidden-Connector motherboards from ASUS and MSI. It supports E-ATX (12"x10.5") boards including ROG MAXIMUS Z790 HERO BTF, ASUS TUF GAMING Z790-BTF WIFI and MSI Z790 PROJECT ZERO. The case offers a three-way GPU installation (floating, vertical, forward-facing) with a 400mm PCIe 4.0 riser cable and floating GPU bracket included, interchangeable front panels (tempered glass or perforated), extensive radiator and fan support, and multiple removable dust filters for easy maintenance.

Advantages

The chassis provides flexible GPU mounting options and a pre-configured PCIe 4.0 riser cable for reliable 16GT/s data transfer. Dual interchangeable front panels allow prioritizing aesthetics or airflow. Designed around the CTE Centralized Thermal Efficiency concept, the rotated motherboard layout separates CPU and GPU airflow paths to improve intake and heat extraction. Large cooling capacity and generous component clearances enable high-end custom builds with extensive cooling configurations.

Key specifications

• Compatible motherboards: E-ATX (12"x10.5"), supports ASUS and MSI Hidden-Connector models listed (ROG MAXIMUS Z790 HERO BTF; ASUS TUF GAMING Z790-BTF WIFI; MSI Z790 PROJECT ZERO)
• GPU installation: three-way (Floating, Up Right vertical, Right Forward forward-facing) with included 400mm PCIe 4.0 riser cable and floating GPU bracket
• Riser cable standard: PCIe 4.0, 16GT/s, up to 64 GB/s bi-directional
• Radiator support: up to 420mm (front, rear, M/B side); AIO up to 420mm/360mm (front, rear, M/B side)
• Fan support: up to fourteen 120mm or twelve 140mm fans
• CPU cooler max height: 166mm
• VGA clearance: up to 443.8mm (without radiator)
• PSU length support: up to 220mm
• Drive bays: up to two 3.5" in HDD cage; one 3.5" or two 2.5" on drive plate
• Front/top I/O: two USB 3.0 ports, one USB 3.2 Gen 2 Type-C, HD Audio
• Dust protection: removable filters at top, front, bottom, rear and right side

How to use

Install the compatible motherboard (standard or Hidden-Connector) on the rotated mounting tray, then choose the desired GPU orientation using the included floating bracket and the 400mm PCIe 4.0 riser cable for floating or forward-facing layouts, or mount vertically in the up-right position. Fit cooling components in available locations: front, rear, bottom and M/B side support radiators up to 420mm and multiple fan mounts. Place storage drives in the HDD cage and on the drive plate as required, connect PSU (up to 220mm), and use the top I/O for peripheral connections. Remove dust filters for regular cleaning to maintain airflow and cooling performance.

Recommendations

For optimal thermal performance, install separate intake fans toward the front for CPU airflow and exhaust fans toward the rear for GPU heat extraction, and choose the front perforated panel if your build emphasizes maximum airflow. Use the included PCIe 4.0 riser cable for floating or forward-facing GPU layouts and verify GPU clearance when planning radiator placement.
