iOS Remote Compiling: Is a Mac Mini enough?

Hi,

I am thinking of using a Mac Mini as a remote server to build iOS projects, which need XCode for compiling. Since I do work on a Windows machine I'd only use the Mac Mini for building, nothing more.

Do you think there's any major difference in a 1.4ghz or 2.6ghz CPU if it only comes to CLI building?

Is anyone of you using a Mac Mini already and can tell from experience?

Thanks in advance!
