UCTRONICS 19” 1U Rack Mount for Raspberry Pi with SSD Mounting Brackets, Thumbscrews Front Removable Bracket Supports Up to 4 Raspberry Pi 5, 3B/3B+, 4B and 4 SSDs, Option SD Card Adapter

Loved this little pi mount for my mini rack. I put 2 pis in the currently for pi hole and then another for OMV and its working great and looks super clean! Looking to get another Pi in there for some additional stuff but for now clean and effective

Nice 1U panel that holds 4 RPIs. My Pi's are mounted safe and secure!The thumb screws are a really nice addition. They're mounted to the frame that slides into the rack and are spring loaded. It's nice to not have to worry about loosing these or them shooting across the floor if you drop one.The fit is tight and right. Everything fits perfectly. I have a Pi4b and two Pi5's loaded in the rack now and it gives them a nice professional fitting where they're safe from being knocked around or dropped.I guess you can fit a hard drive underneath but I couldn't get my seagate to fit - it is a usb portable, so there's a case that increases the height of the drive. a standard internal hdd would probably fit though.One drawback is that the mount standoffs are part of the individual mounting frames for the pi's. If all you're doing is mounting a Pi with nothing that needs extra space it'll work fine. But my Pimoroni ssd card that mounts under the Pi pushed everything out of the way. Tried different mounting configurations but really is meant to be mounted the way the manufacturer wants it to be mounted. In the end I just cut them off and used ordinary standoffs.

Good value for a niche rack mount solution. Buying a second one right now. Other reviewers had a bad experience using PoE hats in conjunction with the rack but I had no such issues using the UCTronics brand PoE hat. Don't have others to try but it works well with their own hat. The only issue is that you can only use two of the four screws to mount the board to the tray, as the other two screw holes are covered/used by the hat. You can do it if you have longer screws with the same threads but the ones supplied with the unit won't go through a hat, spacer and pi to reach the tray.

Overall works pretty good, pretty will design. Great for filling spare rack space with a few PIs. just be careful if trying to use hats on your PIs, the header pins easily bump into any equipment mounted above if your messing with it and will short out your PI. Not their fault but just a heads up.

Very nice way to organize your pi's. Works well in our environment with a standard size rack. One thing I would absolutely recommend is finding some cables that work at a right angle. Makes things much easier to organize and fit together. Overall, a good value for the right situation. Little lighter than what I wanted but it seems to be holding up overall.

I have a19" rack and although this did not fit out of the box, with a little tweaking it fits fine. My Raspberry Pi's fit in nice with fans and SSD drives under. Using a SATA cable for ssd's requires a little tape or something so they do not easily fall out. Just what I needed!

I just installed four Pis in this case. While the case is designed for the Pi 4 B, the Pi 3 B and 2 B fit in it, too and I suspect the four-USB-port Pi 1 B+ will fit into it too. (The original Pi 1 probably fits too, but would have some empty space around the USB ports.)The boards mount securely to little daughter cases using supplied screws (mine came with two more than the sixteen required). On the bottom of each daughter case is room for a 2.5" hard disk or solid state drive, and screws are supplied for this as well. You'd need to supply your own USB 3.0-to-SATA-and-power cable/interface, and you'd need to ensure that your power supply had enough amperage to properly power both the Pi and drive, but this is a nice touch. The four daughter cases connect to the main rack-mountable portion using thumb screws that also have Phillips heads in them, in case you need help loosening them.Running the power cables to the Pis is a bit tricky, so you may want to connect them before you put the whole thing into your rack.The status LEDs of the Pis will be invisible using this case, since they'll be inside the rack, but the Ethernet ports are fully exposed at the front of the case, along with the USB ports. You can, of course, see the network traffic LEDs easily from the front, so have a pretty good idea if your Pis are functioning okay.There is limited space to label anything, but I was able to put some labeling machine labels on the case vertically with machine names, so I know which is which.This is a nice case. It's not super inexpensive, but as rack-mount stuff go, it's reasonably priced, and it's certainly thoughtfully designed. I would buy it again (and may get another yet).

I am totally disappointed with the quality of this 19(ish) rack mount. Without my handy Dremel, this wouldn't fit in my 19" 2 post rack that already has multiple enterprise grade switches and keystones. The mount holes for the trays are so brittle, the slightest movement of the tray from plugging in a micro-HDMI cable or a USB flash drive will break the mounts away from the frame. It is flimsy and not a good value for the cost.With some extra effort, power tools, new nuts and some supper glue, I was able to make it work for me.Ease of assembly = 0/10Build Quality = 2/10Functionality = 3/10Fit = 0/10Value = 3/10
