Looking for recommendations: PCIe wireless-ac NIC card

I want to find a good but inexpensive wireless NIC to put into a micro desktop that’ll work with linux (specifically UB, of course) on the 5GHz band. Out of the box would be great, but I’m willing to do some work to make it work. I’ve found some that might work, but I figured I would ask if anyone here knows of something that actually will work. Computer is an Intel i5 Sandybridge Desktop.
