The Supermicro SuperChassis 745BTQ-R920B is a high-density, enterprise-grade storage chassis engineered to handle demanding workloads with reliability and expandability. This 4U tower chassis blends robust cooling, a versatile drive ecosystem, and proven enterprise features to deliver a scalable foundation for data-intensive applications, virtualization, HPC, and cloud storage. It is designed to support a broad range of motherboard standards—EATX, ATX, and Micro ATX—making it an ideal backbone for custom server builds, NAS appliances, or IT infrastructure upgrades where performance and uptime matter most. With dual 920W power supplies already installed, this chassis emphasizes redundancy and availability, reducing the risk of power-related downtime during peak workloads. The 745BTQ-R920B also focuses on serviceability, featuring front-access bays and a backplane that accommodates a variety of SAS/SATA drives, enabling flexible configurations from midrange to high-end storage solutions. In short, if you need a sturdy, expandable, and future-proof chassis capable of hosting sizeable drive arrays while maintaining easy maintenance, the 745BTQ-R920B is engineered to meet those demands.

  • Exceptional storage capacity and flexible expansion: This chassis provides 11 internal drive bays plus 3 external 5.25" bays and 8 external 2.5"/3.5" bays, delivering a versatile platform for SAS/SATA drives, SSDs, and HDDs. Its expansive drive ecosystem supports combinations of high-speed SSDs for caching and large-capacity HDDs for bulk storage, enabling tailored configurations for performance, capacity, and cost efficiency.
  • Redundant power with reliable uptime: Equipped with 2 x 920W power supplies installed, the 745BTQ-R920B emphasizes uptime and resilience. Redundant power supports uninterrupted operation during a single PSU failure and reduces the likelihood of power-related outages during intensive workloads. The design favors hot-swappable or easily serviceable power paths to minimize downtime during maintenance.
  • Broad motherboard compatibility for flexible builds: The chassis supports EATX, ATX, and Micro ATX motherboards, enabling a wide range of server and workstation configurations. This flexibility is ideal for IT environments that require customizable compute nodes, GPU or accelerator cards, and RAID or HBA expansions without sacrificing chassis form factor.
  • Advanced cooling designed for 4U class workloads: With 5 x 3.15" fans installed, the 745BTQ-R920B emphasizes robust airflow to keep CPUs, PCIe cards, and storage controllers within optimal temperature ranges. Efficient airflow paths and fan placement help maintain performance under heavy I/O, extending component life and reducing thermal throttling in dense storage deployments.
  • Front-access storage and modular expansion: The combination of 3 external 5.25" bays and 8 external 2.5"/3.5" bays paired with a SAS/SATA backplane affords easy access to storage components for maintenance or expansion. The front-access design minimizes downtime when swapping drives or upgrading storage while maintaining a clean, serviceable interior for upgradable controller cards and cages.

How to install Supermicro SuperChassis 745BTQ-R920B

  • Begin with a clean, vibration-free workspace. Verify you have the correct motherboard form factor (EATX, ATX, or Micro ATX) and that your drives, backplane, and expansion cards are compatible with the chassis.
  • Place the chassis on a stable surface or rack-compatible stand. Ensure all fasteners are readily accessible and that the environment has adequate cooling and ventilation.
  • Install the motherboard using the appropriate standoffs for EATX/ATX/Micro ATX. Align I/O ports with the chassis opening and secure the board, ensuring no cables interfere with fans or PCIe slots.
  • Populate the 11 internal drive bays and 8 external bays with SAS/SATA drives or SSDs as your storage strategy dictates. Install any required backplane connectors and ensure all drives are properly seated and secured.
  • Connect the dual 920W power supplies and route power cables to the motherboard, backplane, and expansion cards. Attach required data cables for SAS/SATA controllers, hot-swappable backplanes, and front panel connectors.
  • Install any additional PCIe cards or controllers as needed, keeping airflow in mind. Double-check clearance around fans and PCIe slots to prevent cables or components from obstructing cooling paths.
  • Power on the system and enter the BIOS/UEFI to configure drive modes (AHCI/RAID as applicable), boot order, and any chassis management options. Verify that drives are recognized and that all fans operate correctly.
  • Perform a basic POST test and run initial diagnostics to confirm stability. Apply any firmware updates for storage controllers or管理 modules if available, then finalize your deployment with your preferred operating system installation.

Fantastic foam!
Color: Black, Color: Black
Bought this so I can cut down on my trips to Starbucks and recreate those drinks "to go" at home. It works for making any kind of foam...most recently been whipping up 1/8c half n half with it and added syrups for my iced coffees I take to work. Soooooo worth the money. Starbucks quality foam (if you're not a coffee snob) at home. I now enjoy having iced coffees with salted caramel or chocolate creme cold foam that costs less than $2 to make at home versus $15 at the drive-thru. Time & money saved!

Favorite kitchen gadget!
Color: Black
I bought this for mixing powdered mixes into water, and boy do I love it. I honestly use it way more than anticipated and it works so well. I use it for everything from whisking formula to the intended purpose of frothing milk. Blends quickly and clean is easy, just put a couple of drops soap into water and turn on them rinse! Best money I've spent recently on something for the kitchen, don't even hesitate, just buy it!

Spiral portion of blender did not hold up
Color: Black
It was wonderful for 10 weeks. We used it almost daily and sometimes twice a day. It frothed quickly. It proved a satisfying blender until approx 10 weeks of use. The wire spiral on the end started to slowly wind off. It worked OK but wobbled and frothed weakly at that point. For short term use, for very infrequent use, it will be fine. Looks acceptable, easy to use. Changed the batteries one time. For the price, I am not unhappy. Have now replaced it with a more expensive one on Amazon. Thank you Amazon for giving your shoppers the opportunity to leave our feedback. It is one of your most appreciated features.
