Cons: Its been about a year and the USB ports are almost dead. Wireless HID devices and card readers will work, but anything requiring a good amount of power wont like external hdd's, or a ipod/zune/phone will NOT. I kept getting delayed write failure erros, and thought it was windows but through a ton...
Cons: NIC changed to Realtek 8110 which isn't compatible with some Linux Distros like CentOS4 I have been using these for about a year with CentOS 4 for a backup box. The last three have a different NIC built in and that sucks.
Summary: For what it is, a entry level package, its pretty good. I bought it for a small HTPC and it worked great. Installed Ubuntu + MythTV and it's great. Was even able to get video acceleration working through xvmc. That and a relatively low powered cpu (3600+) plays 720p h264 video beautifully.
Pros: Works just fine - after bios update. Gigabit Ethernet, onboard video, small package.
Summary: The bios does need to be updated to support current generate cpus. You will need to download the latest from http://support.asus.com and use afudos.exe off the included CD.
Pros: I've built dozens of systems based on this barebone, along with MANY other Asus models. These work like champs. These are designed for basic computer use, office work, web and email, etc. The power supply may be considered small, but it's more than enough to power what it's got.
Summary: To update the bios first download the latest bios for the ASUS M2V890 barebones from Asus's website. Next: Google Asus Update Utility - Download/Install this. I downloaded from MajorGeeks.com. After the Asus update utility is installed run it. Select the option to update the BIOS from a file.
Pros: Stable Inexpensive Decent Drive Support
Cons: Lack of documentation on how to correctly update the BIOS.
Summary: I am a professional computer tech and have overall understanding of computers, but let me tell you this, this is the first time i got stumped! dont buy this barebone unless you check to see from asus what cpu's work.
Pros: cheaper than most. quicker because its already assembled.
Cons: do not use the AMD 64 LE-1600 cpu, it will not take it! i tried 5 hrs of bios searching to get it to update or flash. finally after all of that i came to the conclusion this cpu is not capable of working right unless you wish to press F1 to continue every time. I replaced the cpu with a dual core...
Summary: I strongly recommend that you do not buy this. It's very cheap, and seems like a good bang for the buck, but it truly is not. The motherboard and power supply make this barebones a terrible buy.
Pros: Nice looking case, relatively well put together. Onboard video is of reasonable quality.
Cons: The Motherboard failed after 6 months. The PCI-E slot never worked properly, preventing the use of a video card. The power supply had to be replaced, won't work if you use a video card, or most common hardware, which require a higher wattage.
Summary: You should probably flash the BIOS and get a new power supply. With that being said, mine is running fine on the stock PSU with 5000+ Black, 150 GB SATA HD, Optitec DVD-RW, NVidia GeForce 6300GS, 2 X 1GB Kingston RAM.
Pros: Very cheap (about half the price of getting a motherboard, PSU, and case separately AR), works after some fiddling. IDE & SATA inputs. Small footprint. Works.
Cons: Had to flash the BIOS to get it to recognize my 5000+ Black Edition (still worked, but had to press F1 to boot every time). Power supply is a bit low powered. A bit cramped inside the case.
