You can buy anything you want out there, but you'll have more fun by doing as much building (kits, plans, speakers, cords,cables) as you can. Of course some things may be out of your ability to do right away, but with practice and experience many types of components and speakers can be built. Start small and as you gain experience you can try more challenging projects. Also, modifying components can bring a lot of enjoyment. As for me, I could never buy someone elses project as long as I knew I could do it myself. If you really need a system now you can look for used gear and learn how to do modifications. Good luck and have lots of fun. By the way, I'm kinda new to this stuff too, and not to brag, but I've made all my own interconnects, power cords, built 2 mono-block tube amps, built large floor standing speakers, built 2 JR power filters, ran dedicated lines all in around a years time. I do have a great brother-in-law who got me started in this by giving me the amps to build, giving me some awesome Focal speakers and giving me much advice and technical help. All the advice and info you need can be found on these types of forums.
So what are you waiting for...get going!
