Server Chassis Guide: Build Your Ideal IT Infrastructure

The server chassis is the backbone of your server setup, housing critical components and ensuring optimal performance. Choose the right chassis to optimize space, airflow, and expandability. Let's explore your options:

Server Chassis by Form Factor

  • Tower Chassis: Versatile and expandable, perfect for growing businesses requiring flexibility and increased storage capacity.
    • Sizes: Full Tower (maximum space), Mid Tower (balanced), Mini Tower (space-saving)
  • Rackmount Chassis: Designed for high-density data centers and server rooms, maximizing space utilization and simplifying cable management.
    • Sizes: Measured in rack units (U), typically 1U, 2U, or 4U
  • Blade Chassis: Ultra-compact and modular, ideal for large-scale deployments where high compute density and shared infrastructure are priorities.

Server Chassis by Brand: Top Manufacturers

  • Rosewill: Budget-friendly, reliable chassis with a focus on rackmount solutions for small to medium businesses.
  • Supermicro: High-performance, enterprise-grade chassis known for their build quality, advanced features, and customization options.
  • Chenbro: Durable and versatile chassis offering a range of form factors and configurations for various IT environments.
  • iStarUSA Group: Specializes in storage-dense chassis with hot-swappable bays and robust cooling solutions.

Server Chassis Buying Guide: Key Technical Considerations

  1. Form Factor: Choose based on your deployment environment, space constraints, and future growth plans.
  2. Size (U) (for rackmounts): Select the appropriate height to fit your rack and server configuration.
  3. Expandability: Consider available drive bays, PCIe slots, and memory capacity for future upgrades.
  4. Cooling: Ensure adequate airflow and fan options to maintain optimal operating temperatures for your components.
  5. Power Supply: Choose a power supply with sufficient wattage and redundancy options to meet your server's demands.
  6. Features: Look for features like hot-swappable drives, redundant power supplies, tool-less access, and cable management options to simplify maintenance and improve reliability.
  7. Brand Reputation: Opt for reputable manufacturers known for quality, reliability, and support to minimize downtime and ensure long-term performance.

Pro Tips for IT Professionals:

  • Thoroughly assess your specific workload and hardware requirements before selecting a chassis.
  • Pay close attention to compatibility with your motherboard, expansion cards, and other components.
  • Factor in future scalability needs when choosing a chassis to avoid costly upgrades down the line.
  • Consult with IT experts or refer to detailed product specifications to make an informed decision.

Rack mount on a budget

Amazing 2U case.

Well built, flexible for wide array of applications

“ My main reason for choosing it was that I needed a cheap GPU server using consumer grade cards (Geforce RTX 3090) which don't fit in a typical server chassis. ”

Great chasis for ATX rack mounted server/pc

“ A large PC style ATX PSU will likely extend over the CPU socket (I was using a 1600w seasonic); meaning you will have to use an AIO/water cooling setup for the CPU, or at a minimum a 2u height cooler (this is on an ATX MB). ”
