ASUS AT5NM10-I Intel Atom D510 BGA559 Intel NM10 Mini ITX Motherboard/CPU Combo

Pros: Silent, fast, stable, and low power.

Cons: None.

Other Thoughts: I use this as a Linux server running Gentoo and I have nothing but smooth sailing with this hardware. Kernel booted on the first try, and it has never not been able to boot. I have had it running 24/7 for over a year now and it just keeps going.

Pros: Cheap, easy to install, quiet, fast when it does work

Cons: I never got this board to be stable. I tried two different versions of Windows (XP and Win7), different memory sticks, different hard drives, different power supplies, BIOS updates. On average it will run for one hour before bluescreening--sometimes a lot faster. I also get random application crashes all the time. ASUS support is a joke--they made me pay the shipping for an RMA, then returned the board to me, apparently without doing anything (they didn't even tell me whether they fixed something or not).

Pros: This board is hard to beat for the price. I'm using these in Asterisk servers and haven't run into an issue yet. I'm only adding a Seagate hard drive and 1 or 2 Gig of memory, but the fact their is no fan needed is one of the biggest reasons I chose this particular motherboard. I sometimes need the available PCI slot also.

Now for the pleasant surprise. Recently bought two more of these (3/8/2011) and after building the systems and installing software, I checked the system info. The info came back as an Intel D525 processor running at 1.80 GHz. I checked the ASUS box, and sure enough, it listed the D525 processor. Older boxes I still have around list the D510 processor, and Newegg's site still has it as a D510. Nice little bonus.

Cons: Nothing I can think of.

Pros: Fast boot and post times. Takes very little time to get to windows resume hibernation screen(against the Zotac LGA775 board)

Fanless

Gigabit networking

Has a parallel and serial....if you need that.

Cons: USB haves problems powering items(read below)

Only one audio out(read below)

The heatsink is pretty hot, however its not bad.

Expensive, the Intel version is cheaper.

No PCIe or mini PCIe slot.

Only two SATA.

More USB ports on the outside would be nice, though there are two or so headers internal.

Other Thoughts: I first purchased the Intel D510 but I couldn't get it boot, only post. So purchased this as a the next cheapest thing.

USB Power problem
It seems to have a problem powering certain items connected to the I/O ports. If I tired to connected my external DVD drive, it would spin. But every thing(PS/2 and other USB) would lose power, the system would stop POSTing and booting. I had to use an internal SATA drive to install the OS. This may be just a problem with my Rosewell USB drive.

This behavior may have something to do with the Intel chipset. I observed this same behavior on the Intel board and discounted as a bad board, but this does it as well.

IDT Audio on board(as I can tell so far) will only allow for one port to output audio. Realtek will let you change the Line in to Line out through the software. This some what limits me because I need two audio outs for the car(have to buy a splitter).

Im running XP SP3 and Centrafuse for a carpc. Powered by Pico M2 160wat

Pros: Good little mobo for the price. I used this to build a little system for the in-laws. Fast, stable, and quiet. I've got it going with 2GB of Kingston Ram and a Seagate 320GB HD. Plays flash at full screen on a 23" Monitor. Great bang for the buck!

Cons: No PCI express but they will never need it.

Pros: Dead silent
Boots fast
More than fast enough for most tasks

Cons: Will not run Flash sites like Hulu in full-screen. The video is choppy, even at low resolution like 360P.

I bought this for the sole purpose of being my HTPC and streaming sites like Hulu, Netflix, etc.. Asus and Nvidia sites rave on about how the Ion GPU will serve up 1080P video. Apparently this is only if the source file is local, because even 360P Hulu streams are choppy. Nvidia's FAQ places the blame on a 1x channel between the CPU and the 2nd gen Ion chip, that cannot process extra info included in some streaming video. It would be nice if they would add this tid-bit to the page where they say it can do 1080P.

I don't have a blu-ray drive so I haven't tested a true 1080P source yet, but I can't grasp how it can process 1080P when it already can't keep up with 360P streaming. And no, the problem is not network related, as the buffer is full, and the choppiness is continuous, not periodic like when the streaming drops out.

Other Thoughts: DO NOT BUY FOR AN HTPC!!

I am really hoping that a future Flash update might fix this. The board is perfect except for this LITTLE annoyance.

Pros: Absolutely silent, don't need any coolers in case installed. Does great job especially with intensive tasks.

Cons: 4GB top is quite a limit, i wish i could put 8 or 16 Gb of RAM on it.

Pros: No issues as of yet. I have been using more pricey Pinewood-based boards for 1U servers, but this box is not mission critical so I thought I'd try this board that costs half of a Super***** board. I also used a leftward 1U right-angle PCI adapter to install a PCI card.

Cons: Be aware that this board does not fit a 1U rackmount case due to excess vertical height of the audio connector. I used a Dremmel to cut a rectangle in the case top so the board would fit properly. With the case on, it's still a true 1U, so the audio connector is just a mm too tall.

Pros: No problem at all. Running Freenas, shows 4 CPU (2 core + HT), 60MB/S transfer speed on large files.

Cons: none

Pros: No problems installing in an Antec NSK3480 case. Runs cool as expected, what with the large passive heatsink over the cpu and the chipset - as well as dual case fans.

Transferred over a WD 160Gb SATA with WinXP Home upgrade, 2Mb of Crucial 2GM CT2KIT12684AA800 DDR2 memory.

The Win re-activitation went without a hitch.

I'm using the on-board graphics controller, appropriate for this board. It's connected to a 15" HP LCD monitor with speakers.

The on-board serial and parallel ports are unusual these days - my guess is that this MoBo is useful for business/industrial uses, where connectivity to legacy peripherals is important. There's a MoBo COM2 header for those that are interested in such.

No issues with with the on-board LAN device.

As per usual for newegg, it arrived on time.

Cons: Minor issue - the Antec case I have has a wide power-on pigtail that I couldn't connect - not a problem; I know when it's on!

The other front panel connectors fit OK.

Other Thoughts: In use just for about a week - so far, so good...
