I do, I just picked up a fifth 7970 and I still have two slots on a motherboard to fill. I am going to use mining proceeds to pay back the loan. I currently profit 475/month from mining and all my equipment has already paid for itself. After adding the cards my profit would be somewhere in the neighborhood of 650-675 /month at current difficulty and price. I can make weekly payments from mining proceeds or even daily if that's how it needs to be. Since BFL ASIC and reward halving are right around the corner, I want to get this going soon to get as much profitable time in as possible. I'll even throw in my password to bitjack21.com as part of the deal... Don't expect anything out of that guy though, he hasn't responded to any of my communication.
EDIT: I have logged on to bitjack21.com and attempted withdrawl and I was able to get 3btc out.. We'll see if this continues or if it is just a fluke.
Nevermind, all this difficulty increase lately has got me worried, I don't think it would be prudent of me to request any funding for mining at the moment. Thanks for your consideration.
