Well, I enjoy tinkering with stuff and putting things together, but there is the unfortunate problem I mentioned earlier. At least for me, it doesn't seem to matter how carefully I do everything, something ends up not working. When I did a MOBO replacement several years ago I ended up with a system that wouldn't power up at all. A friend with more skill was able to fix the problem by disassembling a plug, separating its connectors, and basically fitting them one-by-one into the connectors. I still don't know how in the world he came by that knowledge. But that's just one of many examples of how things just don't work as advertised and require special, insider knowledge to get working. In short, it all looks so easy when somebody else does it (or when you read instructions or guides), but when you're actually in there doing it, you discover you don't know enough to really make it happen (unless you just get lucky).
