Hi guys Ive been debating an Imac but have since been put off due to the limitations regarding upgradin it. Ive been thinking about an old macpro as Ive heard they can be jsut as good if upgraded a little bit. Can anyone help me out a bit with this? Im not really sure what to look for when buying one, will any display work with them? And what are there limitations, are the motherboards quite slow, does the ram have to stay at the slower speeds etc.. http://www.ebay.com.au/itm/Apple-Ma..._Computers_Apple_Desktops&hash=item20f53a2037 Ive been looking at this model, what do you think? Any advice would be great.
