Speaking of computer hardware, I myself would like to start mining from home on my own. I know with the next few difficulty increases I will mine less and less but I also need/want new components for my gaming rig.
I don't know as of yet which motherboard can take 2 Video cards and am planning on getting 2 ATI 5770's. Ram I only want As cheap as I can get and a good enough PSU.
It's a modest rig that will output around 360Mh/s. You can mash up something from this list https://en.bitcoin.it/wiki/Mining_rig
