I just want to see a detailed picture of the inside of an Intel Core2 Quad desktop, so that I can compare my internal connections with an accurate model. I'm not very tech-literate, but I'm also broke and need to try to fix the connections myself.
A typical Core2Quad system is going to look a lot like any other ATX system anywhere from a P233MMX or K5 to an i7-3770k or A10-5800k.
They all follow the same general ATX guidelines and most connectors are keyed to only fit in one particular location and orientation. For the few connectors that may look identical but serve different functions (ex.: USB2 vs 1394a front-panel headers), the only ways to tell are to either look for hints on the PCB's silkscreen or read the manual since locations for minor items can vary considerably between vendors or even between product lines from the same vendor, rendering a picture from a 'typical' C2Q that does not use your specific motherboard nearly worthless. The only universal connector locations are the expansion slots (100% standard) and the ATX12V (4-pin or 8-pin connector near the upper-left corner), everything else varies a lot.
Looking at pictures might confuse you more than it helps unless you have a picture of your specific board, preferably one with overlay labels for all important connectors.
