Read your own notes to yourself. I was just looking this over for my board today as well. I have an Asus M2NB. My board is not AM2+ and I checked the bios updates that were not all that specific, just said support updated CPUs. As I recall reading when I bought this MB on sale for $85US, as a gamble, it was supposed to be future compatible with AM2; but AM2+ was not in the cards back then but the socket was supposed to support the Phenom CPU. For what I spent I was willing to dump the MB for something else, I was interested in a good solid business MB in the lower price range. It had onboard Nvidia GeForce 6000 on the PCIe bus. The experiment was worthwhile, just not going to be my gaming platform.
That onboard chip never liked the memory I put in which was matched Corsair 6400s. As I followed this MB board over the months the RAM specs suggested by Asus changed continually until the RAM I bought off the Asus advisory was completely off the list.
I'm going to dump the board and put it in the wife's new PC for Christmas.
I was just over at Crucial.com today looking over this
2.5inch external USB SSD adapter kit, that can also accept a 2.5 mechanical drive in SATA 3.0 only. As I work on a lot of laptops too, and backup the drive image of a laptop before doing anything, I currently have a 2.5 mechanical PATA adapter in a 5.25 bay. This unit I'm talking about is offered by Crucial for $30US. Their 65Gig SDD drive is 399 now, which is cool for those backups a mission critical business needs. But, I'm just looking to backup laptop drives, SDD and SATA 3.0 as these become more prevalent in my area. I also noticed that under the Lexar brand, Crucial is selling a 16GB SSD for the Express Card slot for only 60US. That drive comes with what looks like promising backup software.
Good luck with your new rig.
