Linux based OS just for RDP

I am currently seeking a distro (if one exists) that basically mimics a thin client, I have found a few but none seem to be what I'm looking for. The OS will need to be installed on a client PC (no PXE, or server based image deployment) and requires an RDP client...thats all. I realize some distros can be stripped down and configured to do this however I do not have the linux knowledge nor time to do such a thing. Any advice would be appreciated. Thanks Jeff
