Pros: I bought this as a DIY router kit, and it excelled at that. Ran pfSense on it for most of the time, then ran Debian Wheezy as the software. I even added a Penguin Wireless N Half Height Mini PCIe Card for GNU / Linux, which worked quite well given the cheap antennae I connected, even in pfSense (FreeBSD based). I would buy another.
Cons: This motherboard died after just over two years of service. I had been trying to connect a serial console, and at some point it no longer boots. The PC speaker does not beep, though the power is connected and the fan does turn on. The HDD light flashes briefly when power is applied (there is no power LED). Since it's no longer under warranty (it expired in May 2013), I will have to purchase another one (or another option).
Pros: Dual Cores and 4 threads with the Intel Atom 525. Low power and 6 SATA connectors. Added 8 Gig, 4 more than advertised as workable. Runs cool even without mounting CPU fan. Even runs MS Windows 8.1 and MS Windows 2K12 R2.
Cons: SATA 3 and not SATA 6. PCI and not PCI express, takes full size micro PCI express and no way to fit in a half-size micro PCI express such as a standard half-size WiFi card. I wish the daughter cards from Jetway included high resolution video, or just even an HDMI or DVI instead of just VGA output on the m/b. The Intel ATOM does not support hardware virtualization technology so, no hyper-v with this board.
Summary: Makes for a great NAS, home server, or generic low-power server solution.
Pros: Mini-ITX, silent, 6 SATA ports, Intel LAN, dual LAN, the list goes on and on. Runs Ubuntu Server 13.04 like a champ. Set up bonding on the ethernet ports and have a RAID5 setup with 5 1TB drives for a home server. Everything works well and has more than acceptable speed. Processor barely seems to be working hard most of the time.
Cons: Won't run Ubuntu 13.04 Desktop without problems. Seems as if the graphics can't keep up. Not really an issue for me, but worth mentioning.
Summary: Bought this for a BSD Unix server/router box. Wanted to use Seagate enterprise drive, but after discovering no 12v on the drive power connecter I ended up with a WD Black drive. Hopefully the long-term reliability will be good.
Pros: Small, low power, efficient, suitable as a "small server" or specialized box. Works well for Linux or BSD server or router.
Cons: Does not provide 12v on drive connector(s), so it's not for use with a Seagate Constellation 2 enterprise drive
Summary: PS: You can actually use 8GB of DDR3 memory in these motherboards, even though they only say 4GB. Works great with ZFS on FreeBSD!
Pros: Ships with 2 gigabit Intel nics, and easily expandable to 5 for another $60 daughter card add on. I personally own 4 of these motherboards (the JNF99FL's) and they have all worked fantastic as NAS's and routers. I am using this at the office I work at as our primary router and firewall, which allows us to split our internet connection off to some of the other tenants renting space in the same building. We all save $$ and get a much faster connection speed! I used dedi...
Cons: I really wish the PCI slot was a PCIe! I can never get enough SATA or Ethernet...
Summary: Originally purchased as mini-router for offices, it needed to power on after power loss. Simply setting Integrated Peripherals -> PWR Status after PWR failure to Always On was not enough, you must also disable ErP to have the power come on after it's lost... (Power Management Setup -> ERP Function -> Disabled) This applies to the JNF99FL-525 motherboard itself.
Pros: Low power, small system, 64bit OS compatible, running CentOS 6.3
Cons: I was disappointed that case for this system is too short to make use of a half-height PCI card.
Pros: The chipset and LAN are on the Untangle list of known compatibles, so we jumped on this. We have ~5 in the field for the SMB clients, about to deploy another 3. Doing site-to-site VPN's, being the primary firewall for 50+ employees behind a 50/5, constant heavy load - the unit has been very reliable. I suggest going with a 64gb Samsung 830 SSD and a 4gb Laptop SO Dimm.
Summary: Great Atom box. Currently runs Linux on my lan serving as a router. The small power consumption makes it an excellent choice. I have no problems running Linux 3.x kernel on this. Make sure to purchase a 2.5" HDD as a 3.5" will not fit obviously. Laptop memory is also required.
Pros: Great little atom box. x64 dual core Atom chip, dual nics, small, small power consumption.
