UCTRONICS Ultimate Rack with PoE Functionality for Raspberry Pi 4, 19" 1U Rackmount with PoE HAT, All IO on One Side, OLED Display, Power Switch, and Cooling Fan

I got 4 of these to move some Raspberry Pi-4B's to USB/SSD, I also obtained the UCTRONICS Ultimate POE rack mount. While I'm generally happy with this whole configuration, I found that the cables can all be a little sensitive to even the slightest movement, which results in the device connection being lost. I 3D printed a support/restraint for the SATA cable and that stopped issues with the hidden connections being inadvertently moved/disconnected while working in the back of the network rack. I'm monitoring the USB jumper cables to see if they are still sensitive to work being performed in the network rack. I had some issues with a Corsair Force GT 240GB SSD drive, which would sometimes under heavy write loads drop power causing a crash, I was able to reproduce on several Raspberry Pi's and UCTRONICS SATA-SSD adapters, but unable to see the same issue with other SSD devices or with the Corsair SSD connected via another vendor's SATA-SSD adapters, so I suspect this may be some odd incompatibility, so I quit using the Corsair SSD and have not seen any further issues. Update: I'm no longer seeing any issues with the USB/SSD connections, so have to assume the cable strain worked. I did discover an issue when adding another Raspberry Pi 4B, it seems like the board clearance is very tight and some soldered points shorted on the frame causing some strange issues with power, I trimmed all of the Raspberry Pi solder points as much as possible and no longer see any issues. Like others I found the fans to be a little loud, so I replaced them with a version that I had been using with some other Raspberry Pi enclosures and while the fan size was larger, I was able to 3D print a fan shroud that allowed me to add them and reduce the noise to an acceptable level. I still like the product for how it cleaned up my Raspberry Pi farm.

Love the rack. Though setting up may need some understanding and not meant for newbie. The hdmi connection need to be connected properly else it will not work well. Overall am satisfied with it.

Se ve increible en el rack, producto de excelente calidad, fácil de armar.

If you are buying this empty rack mount panel, note that it is not quite the same as the panel that comes in the pre-assembled complete kit. Namely, all of the screw posts for the OLED screens and screw holes to mount your RPi’s have a nice thick layer of powder coated paint on them. It made pushing screws through those holes difficult. And threading nuts onto the OLED mounting posts NEARLY IMPOSSIBLE. I had to run around town finding an electronics kit that included an M2.5 nut driver and then, using the nuts, thread, unthread, thread, unthread over and over again to slowly remove the paint off the OLED posts. In was a massive pain. What should’ve taken something like 20 minutes to slap together took several days including driving around to various hobby, electronics, and hardware stores looking for that nut driver. Also there’s a layer of paint at the base of those posts so thick that the screens don’t quite sit flush with the front. Looks nothing like the pre-assembled unit, which has better fit and finish over all. I think I saved some money on the parts alone by buying the complete kit first, mounting two RPis to that and reusing the remaining screens and hats on this blank panel for two more RPi’s (these panels are installed at different locations). But the hassle and extra expense on tools and gas made it not worth it in the end.

Unit functions as expected. Had issues building, for a high priced item had frustrating experience installing components as the screw holes would not align perfectly. other than that works perfectly.
