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).

Overall Review: 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.

Pros: Fair price, ECC

Cons: None

Overall Review: After installing these I ran memtest on them for 16h or so. No errors.

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

Overall Review: 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.

Pros: - Amazing screen - keyboard light - light

Cons: - small amount of backlight bleed on some edges. Doesn't some up under standard use but can on movies. - keyboard is a little squishy in the middle and is missing a few dedicated keys it would be really nice to have. - 4GB - HDD instead of flash drive - average battery life

Overall Review: I don't want to sound negative with the list of cons, just trying to be up front about the things that detract from it getting a 5/5 rating. So far it has been a really good machine and I love it. Linux runs really well after a little googling. It is also possible to fix the 4GB, and HDD problems if they turn out to be too much of a problem.

Pros: quiet watch dog timer settings to auto power on after power failure supports 2 - 2.5 drives + a small eide DOM drive 2 gige ports

Cons: only 1 set of hdd rails included back plate is flimsy usb ports are real tight so you can only use 2 at the same time if the devices are real thin

Overall Review: nice little, low power server. I made a 2nd set of hdd rails and am running the OS off of the DOM module, and have the 2 hdd setup in a raid config. Its absolutely silent when the hdds are spun down, which is a lot of the time since the because the OS and apps are on the DOM
