Recently a lot of questions from SO has been migrated to SU, which seems to have been given the impression that it is the SO and SF dumping ground, which I strongly disagree with.

However, there is a few questions regarding the setup of developer machines, hardware and software related, and although I agree that it is SU material, the audience is not as wide for these as SO. 

Part of the problem is that some users end up pointing back to SO saying the question is a duplicate. The other part of the problem is that some SO users want the question migrated to SU, and some SU users wants the question migrated to SO. Confused much? *(There is one particular case where the same user couldn't make up his mind, first he wanted it on SU, then decided it should go to SO when it did move)*

*There is no way to flag a question as duplicate cross-sites, the best solution is to post a related question link to the other site*

Examples:

[Building a fast Visual Studio Machine](https://superuser.com/questions/44926/building-a-fast-visual-studio-machine)  

[Help with developer machine hardware and software setup](https://superuser.com/questions/7844/help-with-developer-machine-hardware-and-software-setup)  

[Can all in one desktops be good developer machines?](https://superuser.com/questions/42353/can-all-in-one-desktops-be-good-developer-machines)  

[2009 Ultimate Developer Rigs](https://superuser.com/questions/20631/2009-ultimate-developer-rig)

So where should question regarding developer machine setups go? SO? SU? Non?
