Hi folks, Motherboard with sound card onboard AMD CPUs - 2 RAM DDR3 1333/1600 - 8G/16G OS - Linux/Unix 64bit Virtualization software - Xen/Vserver/KVM 10 Mail servers to be installed I haven't built server box before. Actually I'm prepared to build a new AMD Phenom II X4 955 box with 8G DDR3 dualchannel RAM to test server consolidation/virtualization. However the cost of components for this new box is NOT cheap. Therefore I have another idea adding some more cost building a server to satisfy my curiosity in parallel gaining experience on its building. At the beginning I'll run single CPU and 8G RAM and expand to 2 CPUs and 16G RAM later. In fact an AMD dualcore CPU with 4G RAM onboard can do the job for me. I have an AMD dualcore box with 4G RAM, dualchannel, onboard running 20 mail servers without problem. I'm considering that it'll be no reason to build a new PC on components of yesterday. Therefore I shed my eyes on AMD Phenom II X4 955 as the target CPU on the new box. Kindly provide me some suggestion on; AMD CPU - Opteron OR AMD Phenom II X4 955. Opteron is a true server CPU Motherboard - for 2 CPU supporting min. 16G dualchannel RAM with onboard sound card. Graphic card - I prefer having it onboard. However it is NOT a must. Because all servers are headless, not requiring video card, monitor and mouse. I'll configure the servers remotely on a workstation on LAN. If w/o onboard video card I'll put an old graphic card on the PC in case of need. I have no budget in mind. But this new PC is for testing NOT for production. Therefore I expect saving some cost if possible. Thanks B.R. satimis
