Pros: Zero problems. Works perfectly out of the box with Linux. Price/performance ratio is impossible to beat.

Cons: I wish it had a higher boost frequency. There is a higher clocked version of this CPU (EPYC 7371) but I wasn't able to find it anywhere.

Overall Review: Perfect Linux support. 'sensors' reports an idle temperature of 34C and I have never seen it above 60C even under load. What's nice about this model is its simple and predictable turbo behavior, i.e. all cores run at 1.2Ghz when idle and at 2.9Ghz when under load (all of them) regardless of what instructions are being executed. This is in contrast to some Xeons that have tricks like "4 core boost" which is higher than "all core boost" and then they slow down even more when executing AVX instructions. Linux sees it as a 4-node NUMA system. Make sure to install and run 'numad' and that NUMA balancing is turned on for your kernel, i.e. $ cat /proc/sys/kernel/numa_balancing I was a bit worried about NUMA getting in a way, but this thing is running several KVM VMs at 97% of bare metal performance and without any side effects. I built this EPYC server around Supermicro AS-2013S-C0R barebone system, which I also recommend.

Pros: Inexpensive, nice and easy to understand BIOS. Lots of overclocking features which I won't be using :)

Cons: I have had a similar experience with Adam C. Some memory slots cannot be used: the board won't POST. I have 4 RAM sticks, 8GB each, and I could not get it to run in 4-channel configuration which is what the manual suggests. Also, one slot makes a 8GB RAM stick report as only 4GB resulting in 28GB total instead of 32GB. Weird.

Overall Review: It works though. I did manage to find four "good" RAM slots where my memory works and is fully recognized.

Pros: Legit data center grade hardware.

Cons: It's always out of stock everywhere.

Overall Review: I have a small "home lab" with a few always-on devices and I am using this motherboard for a Debian Linux server which runs a handful KVM VMs. Prior to getting this, I had a generic, consumer grade MSI AM4 motherboard with a passively cooled video card and a Lantronix KVM-over-IP for remote management. Using a proper IPMI motherboard like this is so much nicer! First of all, the power draw and the heat is lower, it's only 25W on idle and the CPU is 4C cooler. THe IPMI interface is also much more powerful than Lantronix, i.e. you can turn the server on/off, flash BIOS, read hardware sensor readings, etc. The web interface is much nicer looking than Supermicro's too. The only minor complaint is that on the first boot, the board spent about a minute initializing the BMC and then the screen went dark. After cycling the power, it turned on but couldn't boot from the NVMe drive. After resetting the BIOS to the factory-default mode, it finally booted. Maybe I've gotten a used board? Not sure... Now it works great.

Pros: Price/performance.

Cons: Not the fastest.

Overall Review: I usually go with Samsung Pro, but they're insanely expensive for 2TB. These are slightly slower but more reasonably priced. Have two of them in striped RAID configuration. No regrets.

Pros: Nicely made. Sturdy.

Cons: Do not fit standard round hole racks. Covered in grease.

Overall Review: Not sure why nobody mentions this in their reviews, but the L-brackets that come with these rails are not compatible with round-hole racks. The holes on the L-brakets are too close to each other, so I couldn't fit two screws per bracket, i.e. my 4U server is mounted using only four screws. It's OK I guess for a single outlier, but do your research carefully if you're ordering a bunch of these. This is in contrast to Supermicro chassis+rails that I had zero problems with.

Pros: Native Linux support. Lowest idle power consumption of any GPU currently (Feb 2019) on the market, about 4-5 watts. That's why it does not have a fan, it really doesn't need it if your case is well-ventilated.

Cons: I wish it had a display port.

Overall Review: If you don't game and don't need 4K this thing is ideal. Also, Linux supports it out of the box with all features you'd care about: desktop acceleration and power management. I am using two of these in headless (i.e. no monitor) home servers.
