Can you get a decent rig..WITHOUT building it yourself?

....and a flux capacitator"...

nah, you dont need one nowadays. i for one use cold fusion reactor for all my "energy-stuff" things.

of course you can get one. most pc building sites offer pre-built pc.

the way i see it, pc building is for more enthusiastic pc gamers. different games have different needs. for example, you dont need ultra powerful gpu for grand strategy games, but a good processor can help.

also, pc building is easy - you just need to learn it in a responsible manner. i for one learned pc building by buying pre-built pc, then changing its gpu. then i changed ram. then i changed cpu and motherboard. just take it step by step and its a lot easier.

another thing, to qualify as "real" pc gamer you have to remember that there are very strict requirements.
one, you need to have a pc.
two, you need to play games on said pc.

i know, its a lot to ask from novices, but those strict requirements have made us the elite that we are now

I'll second what others have said about it not being as difficult as it seems to build a PC. All you really need to do is buy a book on it, of which there are many available. There are also some online guides which could be just as good, but when I built my first PC I liked having a book. First read at least some of the book/online guide, then go ahead with ordering components.
