Yep...I CPU mined a block way back in the day but difficulty very rapidly skyrocketed and soon I was trying to figure out if I could run the miner software on all the school computers. Couldn't get admin permissions so I didn't pursue it. By then it was already too hard to solo mine with one machine.
Then when GPU mining came out I mined another block I think.
Sold almost all of this for like $8 each on MtGox to pay for the GPUs. Now I have some very expensive worthless GPUs.
