My vote is for a basement Man Cave. I have had mine since 1994, and it works great. I put all my old gear in the den, so nobody feels bad that I won't show them how to operate my big rig. I can crank it without disturbing people upstairs, and I get everything in black, so new gear doesn't call attention to itself. No WAF issues whatsoever. Plus, if I do get any grief, I just pull up some of her recent credit card bills, and that's the end of that.
