Computerbehuizing Supermicro CSE-743TQ-903B-SQ Full Tower zwart

The Supermicro CSE-743TQ-903B-SQ is a black Full Tower server chassis designed for single- or dual-processor motherboards and optimized for the latest Intel Xeon processors while remaining compatible with prior-generation Intel and AMD platforms. The chassis includes a 903 W high-efficiency power supply, eight hot-swap 3.5" drive bays plus support for 2.5" and 5.25" devices, and a cooling layout with two front 80 mm fans and one rear 90 mm fan to maintain stable operating temperatures. Its dimensions are 178 mm (W) x 647 mm (D) x 452 mm (H).

Advantages

This server case provides redundant, high-efficiency power and a hot-swap drive design to simplify maintenance and minimize downtime. The cooling architecture uses multiple high-performance fans arranged for 100% cooling redundancy to reduce the risk of thermal-related performance loss. Tool-less PCIe expansion slots and 6-pin power connectors allow installation of up to three high-end graphics cards, and the chassis can be converted to fit a standard rack if needed.

Suitable for

• Enterprise and small datacenter servers requiring robust cooling and redundant power
• Workstations or servers using multi-core Intel Xeon or compatible Intel/AMD motherboards
• Storage-dense systems needing multiple hot-swap 3.5" and 2.5" drives
• GPU-accelerated workloads that use up to three graphics cards
• Deployments that may later be mounted in a standard rack

How to use

Install a compatible EATX/ATX/Micro ATX motherboard and connect the included 903 W power supply to the board and peripherals. Mount 3.5" or 2.5" drives into the hot-swap bays for easy serviceability, and install any 5.25" devices in the front bays as required. Use the tool-less PCIe slots to fit expansion cards and connect 6-pin power cables for GPU power. Configure fans and drive trays so that airflow paths remain unobstructed, then verify BIOS and OS settings for installed hardware.

Recommendations

For reliable long-term operation, ensure redundant power and cooling are configured and perform regular firmware and hardware inspections. Verify compatibility of GPU length and motherboard layout before installation, and allow adequate clearance around the case for proper airflow.
