[Errant]

Start out with a spare PC if you have one, or the one you're using if you set the computation cycles low enough so that you can still use it. Mining takes a lot of resources. I like using CGMiner for a mining application. Find a mining pool to join and start by mining Litecoin or another coin that allows for 'Script' mining.

You won't be able to make enough to pay for the electricity, but you will have fun, and able to learn enough to decide if you wish to invest more dollars into high end GPUs, which will turn a profit at the current price or maybe even an ASIC miner one day.

Here is a link to some basic info:

Thanks for the info — I will look into it.
