I've tried the Alton Brown method of dry aging on porterhouses and ribeyes. It's OK but a steak can take on a bit of a funky flavor that I personally don't care for.
imo, the best thing you can do for a steak is to let it sit at room temp for two-three hours, salt it and let it sit for another 30 - 45 minutes, then grill it. It's like a condensed dry-aging process.
I did this last week and promptly overcooked the fucking things on a grill using lump charcoal. They were slightly over medium, but still delicious, natch.
Over the next week, we would thinly slice the leftover steaks, then heat with butter in an 8" cast iron skillet over medium low. Oh dear...
