I dont suggest chaintech boards. I suggest getting any kind of MSI, Abit, or DFI. You can find nonexpensive boards from MSI and Abit. DFI will be a little more. Also, dont get a socket 754 system, make sure its 939. Socket 939 wont be expensive either.
The new 939 cores are coming out. If you have a little extra money, i would consider them. But overall, dont go socket 754 and chaintech. I would save your HDD. Then hook them up to a friends computer or your new computer as a slave drive. Then you can extract your data from there.
