MyElectronics 19 inch rack mount 1U for 1-4 pcs of  RASPBERRY Pi.

Product Information

However, if one further assumes only 70 to 80 percent of the rated maximum for the power supply can be drawn at 5V over extended periods of time, then one may be at the limit with the Pi 4Bs.

Adding an NVMe drive, from 2230 to 22110 is easy thanks to a dedicated area near the “rear” of the blade. With the Compute Blade powered off I just needed to remove a screw, drop a test drive in and then secure it in place. From the Linux terminal I was able to prepare the drive for use, including setting the drive to mount on boot. If you need to connect your Compute Blade to a screen then the onboard HDMI port is located between the red anodized aluminum heatsink and a Gigabit Ethernet port on the “front” of the Blade.Standing proud and tall, the ICE Tower fan keeps your Raspberry Pi 4 super-chilled. Looking like a hot-rod, this RGB fan connects to the SoC of the Raspberry Pi 4 using two heat pipes. The unit is held in place using a frame that attaches to the M2 mounting holes of the Raspberry Pi 4.

Reduced noise! We replaced the previous PoE hat fan with a new, more durable and longer-lasting ball-bearing fan Design for Raspberry Pi: Supports installation of 4 Raspberry Pis and 4 SSDs, compatible with any 2.5” Solid State Drive (7mm/9mm) and RPi 4B/3B+, and other B/B+ models Another brand that proves this is the Turing Pi, which has a great model for Computer Modules 1, 2 and 3, but is currently developing a compact ARM cluster Turing Pi 2 for the Compute Module 4. The UCTRONICS 19” 1U supports five Raspberry Pis and five SSDs, making it possible to increase the RPi cluster with massive network storage. This added feature makes it perfect for building a Raspberry Pi cluster. Specs and Features We Loved

It has 5 0.91-inch OLED, 5 PoE Hat, 5 SD Card Adapter, 5 Power Button, and supports Pi 3 and Pi 4. Specs & Features We Loved If you ever need to cluster up to 14 Raspberry Pis and an equal number of 2.5 inch hard drives, you might want to look at the Raspberry Pi Server Mark III case from [Ivan Kuleshov]. The original Mark I design came from Thingiverse, but the Mark III is a complete redesign.
