Yes, there is the Radioscape ZE5101 (one on eBay right now) which is a PCI based DAB card. It's rather old though with little info available so possibly only works on an OS like Win XP, I can't even find a link for the drivers.
If you just want to listen to radio on a PC then alternatively you could get any DVB-S or DVB-T card and access the radio broadcasts over Satellite or Terrestrial. They aren't the same exact data streams that are sent over DAB and I don't know if all stations are available on each platform but you'll have the benefit of the higher bitrate. You'll obviously still need an aerial or satellite link.
