Of course I'm a novice builder (1st try). I have an Acer aspire 1641 that quit working so I'm going to put in a new mobo and cpu. I will be trying to use all the present hardware except the RAM. A little advice sure would be helpful. Thanks. http://www.amazon.com/gp/product/B005OJRGYA/ref=ox_sc_act_title_4?ie=UTF8&m=A1XBPHGHAXLHDG and http://www.amazon.com/gp/product/B0028RXHC6/ref=ox_sc_act_title_2?ie=UTF8&m=A2E03HGVYBRQJB I'm going CHEAP in case I burn something up. This tower will be used for web surfing if I succeed.
