Yeah, I would suggest either Mandrake or Redhat, they are considered the 'Windows of linux'
For running windows apps on linux there are many ways
1. wine - www.winehq.com
it'll run your normal windows programs even games, some not well, but i heard people say they run good.
2. WineX - www.transgaming.com
Simular to wine but uses the DirectX API and is really good for playing games, Mandrake 9.1 gaming edition comes with WineX out of the box I believe, however, WineX is not free unless you get it from the CVS.
3. VMware - www.vmware.com
- runs windows over linux on a virtual disk. I don't think it supports directx nor sound, i myself haven't been able to get it to work correctly. Not free either, but has a 30day free trial.
4. win4lin - www.netraverse.com
- simular to vmware I don't know how it works though, never tried it. This is also not free, but i think there is a trial or something.
