Pros: Fair price, ECC
Other Thoughts: After installing these I ran memtest on them for 16h or so. No errors.READ FULL REVIEW
This review is from: ASRock C2550D4I Mini ITX Server Motherboard FCBGA1283 DDR3 1600 / 1333
Pros: Low power, decent performance (for what it is), more than enough sata ports, ECC memory.
Cons: It bit pricey for what I wanted, I didn't really need/want 12 sata ports, but did want low power, dual nics, and ECC.
It could have better/more usb output only 3 ports supported and you use a jumper to select whether 2 on front or 2 on back.
The video is vga only (yeah I know server that is never plugged in but all my cables had moved or to hdmi etc, so initial setup was a bit of a pain).
Other Thoughts: I built a low power zfs based NAS server with this and a Norco ITX-S4 (separate review) case. Its low enough power that even with the drives installed I could use an external power brick + picoPSU instead of a regular power supply which means its almost silent (I have not done enough experimentation yet to be comfortable with unplugging the case fan).
As measured with a kill-o-watt (at the power) plug
- the 102W brick pulls 2.5W when not plugged into the server
- the server + brick when turned off pulls about 6W. This seems a little high but the network is active enough to being using WOL
- with a 256GB samsung SSD and 2 (I'm still waiting on the other 2) 3.5 drives installed.
* it idles at about 28 W
* running burn hitting all cores it pulls about 38W
* with the drives running and the cpu not being pushed it pulls about 35W
* its peak load during boot has been about 55W
So I could have gotten away with a 72W external adapter instead of the 102W adapter I choose.
The mother board supports both 20 and pin power connectors so I could have gone with a smaller picoPSU with a 20 pin cable. I wasn't sure so I went with 150W picoPSU with a 24 connector so that I wouldn't have to bother with a converter.
This review is from: NORCO ITX-S4 Black Server Case Support standard Flex ATX power supply (NOT included)
Pros: Fairly small. 4 hot swap hdd bays. Decent quality construction (its all metal except for the plastic front).
Cons: The fan is noisy, and only 3 pin (not variable speed). I ended up replacing it with a silver stone suncool 81 fan which is almost silent.
You will want a low power/heat mother board, the chasis setup directs all of the airflow across the hdds, very little direct flow over the motherboard
Other Thoughts: I built a small zfs based nas with this using an ASRock C2550D4I Mini ITX Server Motherboard (reviewed separately). Overall I am quite happy with the setup, at least once the fan was replaced.READ FULL REVIEW
