GIGABYTE MC13-LE3 Motherboard – AMD EPYC™ 4005/4004 & Ryzen™ 9000/7000 – microATX UP 25Gb/s + 1Gb/s LAN

Pros: Dual 25G on board, epyc support, runs non-qvl 48G ECC (Nemix) without a fuss and has pretty solid support for any combination of nics/hbas you can throw at it, not to mention no compatibility issues with any number of enterprise SSDs/HDDs (think HGST/Samsung). The BCM is robust with lots of features. Cons: It hates PWM fans – will not properly cycle up any 4-pin model I could think to throw at it (noctua, cooler master, corsair and be quiet) after power on for more than a handful of seconds. The Post and Beep codes are missing from the manual, and the IPMI times out between 1 and 2 hours following boot (on *ubuntu, anyway), necessitating a reboot to be able to use again. Overall Review: The on board network chip (BCM57502), as one would expect from something of this design, gets pretty hot without direct airflow. It can be made to work in a nice tower case, but it’s obviously designed for a rack chassis with very powerful, loud fans. Still, managed to make everything work fine with Gentle Typhoon 3-pins (remember, no PWM) which idles said chip at about 59 C.
All in all, it’s a solid enterprise product and worth playing with in the homelab. Just do your due diligence and know what you’re getting into.
