My emachine model is C2825. It iuses an MS-6734 motherboard which is small to fit the small emachine case. I cant just get a motherboard and use it as it will not fit. I use an amd chip and want to keep using it. I need a new motherboard and the MS-6734 is not available. Any suggestions on a replacement board?
