they won't give you the choice of installing any soft for free, that's for sure (unless wlmrt goes into wares), plus i think that most of us who custom build our own pc's don't really care about the os it comes with... i started on all build up pc that i ended up changing everything in it xcept the diskdrive ... (even the keyboard died on me damn generic brand) but i got to do as many installs as i wanted and choosed the os's i wanted ... tried four gave up on 2 ...
