Replacing regular light box with ceiling fan support

So I'm trying to replace the standard light fixture in my bedroom with a ceiling fan, and I'm not sure how to replace the box with one strong enough for a ceiling fan. Up in the attic, I got a couple pictures of the current box. It's nailed to a horizontal truss support, but it's also wedged under a 2x4 that is braced across the trusses. See pictures. Should I get a metal box that I can just screw right into that cross brace? Or cur out that brace out and screw a new box to the side of the horizontal truss bottom? Not sure how best to do this. And man there is not much room up there to work.

I suggest removing the existing box and replacing it with a steel 2 1/8" fan rated box. You should be able to screw it directly to the 2 x 4

Thanks. Yeah I ended up taking a Sawzall to that 2x4 brace there, I couldn't get the old box out with it there. Then I got a metal fan rated box with the side mount and screwed it into the bottom of the truss. Seems pretty solid. Thanks for the input.
