It doesn't come included, but you can buy a 3.5" to 5.25" adapter panel from Lian Li or Silverstone that matches the front. Or you can just buy a 5.25" card reader.
the liani one seems to have problems with it being to small for alot of people.. the silverstone one seems to be the best but it doesn't exist on any site, i found it on one site that was in stock but i live in hawaii and they wanted over 35$ for shipping. ridiculous. is there any others? or is that the only choices :/
