I need to replace an older pc that is giving me issues and need recommendations on a inexpensive tower. This pc is used for very basic use - mostly Internet and email. I have a monitor so just want to purchase the tower. I have looked at towers available at local stores - both we're under $450 -- was not sure about the processor - one was an AMD E1-1500 (HP) and the other was a core i3-3240 (Lenovo) any recommendations you have would be appreciated. Thank you.
