If you are interested in mining then I recommend you pick up a usb stick which teaches you the best regarding asic mining which is the only way to mine bitcoin now. The only reason there would be to try and use your GPU or CPU would be to learn those specific modes, and you can have some fun in that vein. I believe you learn those same things and more, especially pertaining to the way mining devices work today, if you use a small asic device.
Personally, I use and recommend the Official GekkoScience Compac BM1384 Stickminer

You will find like minded individuals who do this out of curiosity, and more who do this for the passion incited by the marriage of economic change to a technological advance which involves hands on electrical and software based challenges.
I highly recommend against purchasing a product from any other manufacturer at this time unless it is used equipment from a vetted community member. I will also warn you against any form of cloud mining. There are and have been more scams and an alphabet of government investigations against many cloud mining operations. No matter how much someone tells you X company is safe and you see several things showing you will make a handsome profit do not believe it. I have performed my own investigations in current offerings and there is little but more of the same, or in the slight chance it is not a traditional scam or ponzi, you are still being used for your money as a loan without receiving compensation to make it anywhere close to being worth the risk. Your money is better spent in holding coin. Again, please take heed, there are not any current mining manufacturers offering a solid product except GekkoScience.
If you wish to ask any questions or discuss this further feel free to PM me, I am happy to help.
