The world is round and going round, so all things, questions and answers happen to occure again?!?
So you might wan't to llok at A quiet place to code...
But to me it's just:

1. silence
2. fast server and fast workstation
3. tons of literature, e.g. books, tutorials and references
4. no need to stop working cause the office would close

Have a nice day
All decision is left to your taste
