Great system for a great price. 4/3/2019 8:16:13 AM

Pros: Great low power draw.
Second fastest desktop CPU based on Intels 14NM Gemini Lake little core. (pentium silver J5005 is faster but only because it has 300Mhz higher boost clock)
Could be great low power for a NAS (with pci-e SATA cards), or firewall, or router, or media server, or HTPC with a blueray drive the possibilities are endless. Performs about as well as a core 2 quad on 1/10th the power and supports modern DDR4 and instruction sets.
Hardware accelerated video decoding!
Fanless and quiet.

Cons: I wish the Pentium J5005 was an option for like $5-10 more or it would be nice if intel socketed these processors and we could swap them.
If including a m.2 at least make it a m.2 ssd slot instead of wifi. We can always add USB/PCIE wifi later.
I wish the x16 slots were at least x4. Intel says this CPU is limited to 6 PCIE lanes so this should be possible. As it is now the PCIE is limited to 500MB/s so don't get your hopes up for full 10GbE or M.2 SSD on the PCIE.
I wish this had 4 SATA ports like the J5005-ITX.
Could be nice if it had 7.1 surround outputs on the back like the J5005-ITX especially if this is a 'HTPC'
Would be nice if the intel chip supported HDR since it is targeted as a 'HTPC'
I wish it was PCIE 3 and not PCIE 2.
Wish it came with serial, parallel header cables.
Who puts drivers on a CD in 2019? USB please.

Overall Review: It seems like some of you have a hard time reading the manual.
"Warning: To ensure better graphics compability, the BIOS is set to "boot from Onboard VGA" as default even the user install a VGA card on PCIe slot." So if it only boots with VGA you need to change you BIOS setting.
For the people who say the bios update only works in windows:
Download the windows bios update and get the GLKM file out of there and put on a USB Stick and update from the BIOS like normal no windows required. Or just use the internet updater.
The m.2 is ONLY "type 2230 Intel® CNVi " supporting
I can't wait to see how low the power will go when intel releases 10 or 7NM versions of their little core. Probably won't be until 2020 though.

Snappy but picky 4/1/2019 10:28:01 AM

Pros: Snappy performance, low power draw, great value

Cons: Very picky when in comes to RAM

Overall Review: I am running Gentoo Linux on this machine, meaning that I compile everything locally. The performance is perfectly adequate and is actually better than I expected based on the specs. As an example media-libs/mesa builds in just under 13 minutes, compared with the 3 minutes it takes to build it on my server. That might seem quite a bit slower, but that server has 32 cores and fast disks so my expectations (which based on specs hovered around 20 minutes) were handily beaten. The integrated graphics are perfectly adequate to drive my three monitors (one 4K and two 1080p), so much so that the discrete GPU I planned to use with the board turned out to be unnecessary. Note however that my application is a media computer; gamers might not find the integrated graphics that satisfactory (or might who knows, I have not tested). Hardware accelerated media encoding and decoding is a definite plus for my application. The power draw is very low (about 25W at idle for the whole system, and not much more on high load).

Overall I like this board quite a bit and I can see multiple applications at which it would excel, including but obviously not limited to a media computer (like in my case), a router/firewall, or even a file server. The available PCIe slot could accommodate things such as a big multi-port NIC (for the router role, where the WiFi/BT M.2 socket would also be useful), a RAID card (for the file server role), a discrete GPU (for more serious graphics), and so on.

This all being said, I have to take one egg off for pickiness. The motherboard is very picky when it comes to RAM. I had to return two sets of RAM sticks that rendered the system utterly unbootable (the system will not even POST). The third time was a charm, but beside the aggravation I also lost in the process the mail-in rebate window. It would appear that observing the (very short) list of compatible RAM modules is a must for this board (I can confirm in particular that Corsair Vengeance sticks work fine).

Great Pfsense board 3/22/2019 4:28:47 PM

Pros: Great Pfsense board pair it with a Intel NIC and RAM. Pair it with a Pico power supply
Handles Openvpn with no issues
sips power

Cons: Not a big con but i wish the x16 PCI-e slot was a true X16.
It is very picky about which ram you use make sure its supported
wish it had an m.2 sata slot

Overall Review: Good choice for a firewall

Great MB 2/23/2019 12:08:35 PM

Pros: Fanless, runs off a wall wart 12V supply (w/ATX DC-DC adapter). Runs Linux great. This is my raided NAS storage running AntiX.

Cons: UEFI BIOS sucks!! Took a bit to figure out why my old drive wouldn't boot. Who comes up with garbage like UEFI? A FAT partition?? Really??

Overall Review: Yes - hardware is great. Wish it had two more SATA ports.

Problem booting with HDMI under Ubuntu 18.04 12/22/2018 9:38:53 PM

Pros: MB seems fast enough for a media center computer. Love that it's fan-less. Posted without problems. Price is good.

Cons: I simply cannot get it to boot unless I have a VGA monitor plugged in. It boots with a VGA monitor, and with a VGA monitor and an HDMI monitor (via a surround sound amp to an HDTV). But it will not display anything if only the HDMI output is plugged in.

I've had such a set-up working for years, but the old MB finally died last week, and now 4 hours of frustration later, including fiddling with Linux boot parameters, I'm no further than when I started. It's not viable for me to have a VGA monitor plugged in just the get the darn thing to boot. It should be a completely straightforward to make this MB work with my set-up, but it's now.

Happy to upgrade my review if manufacturer is listening and can suggest a fix.

Silent, Low Wattage Motherboard 4/30/2018 8:34:43 PM

Pros: An ideal motherboard for a PfSense firewall. Full length PCIE slot to accommodate full 4x1gb nic. Motherboard rarely goes above 35 degrees Celsius.
Runs Windows 10 Pro smoothly.

Cons: Motherboard LED would have been nice as it is too silent as there are no fans.
The UFI BIOS has some difficulties selecting VMware ESXi but a BIOS update may fix that in the future.

Overall Review: Yes I would recommend this product.
