I am making a system...(specs in sig)....whose components I am importing from USA (I am myself not in USA tongue.gif)....I will have the PC assembled locally....so I went to the local PC shops here....and when I told them that AMD Opteron is a server based CPU, they said I need a 'server casing' blink.gif excl.gif excl.gif excl.gif ..... So do I need a special casing or what ? secondly, he also said that he will chose the casing, based on the design on the mobo's ports...i.e. the place where all the ports r on the mobo....he will see which casing it fits !?!?!? ....isnt there a standard design which all mobo's must follow..so that all ATX mobo's fit in all ATX casings ??? plus, do i need a special 'server casing', just cuz I am using an AMD Opteron ??
