Your wife is right, family comes first. Since I moved to live with my wife I now run only a laptop and although I understand we have money to invest in a more powerful machine, having a kid is a priority so we need to save for childcare, etc. My wife is the one who wears the trousers....

Also if you want to support any project forget about what we do here, donate money to charity and research groups. What we do is a hobby and a waste of energy (I'm an energy consultant). Don't come up with that crap that you need to have a bunch of computers to heat your house when electricity is not the most efficient way to do so. (example)
