My dad is a light Mac user and would like to upgrade his "basketball base" 15" iMac G4 from 2002 to a more recent model. He does not want a glossy or led screen, so in the iMac that narrows the field down to white (non-aluminum) models, which can presently only be found in the used market. He basically only uses the computer for internet surfing and usually keeps it for a lot longer than the average user. He would like either a 17" or 20" matte screen, so a four year old white iMac with an Intel processor in those screen sizes from $600-$800 or a brand new Mac Mini comes to mind. I am not familiar with cost or brands of 17" or 20" matte screen/white iMac like monitors that would attach well the the Mac Mini since I haven't done the research yet, but if one can suggest a good quality model for under $300 new or used,, it would be appreciated. Would it be a better value to get a four year old 17" or 20" white intel iMac for around $600-$800 or buy a brand new Mac Mini with new or used matte screen monitor for around $800? Thanks in advance for your suggestions.
