Hey im looking to get a mac mini as a 24 hour on machine. Im just wondering how does it stand up to heat if im just streaming and downloading other movies from my main computer? Also how loud are the fans? I hope there not too loud since this will be going in my room! Also i need some help on choosing! Im gonna go refurbished but im not sure which one to get. For sure when i get it i will be upgrading to 2gb ram but heres the simples, i need the most powerful one so please let me know which one would be better! 1.83ghz Core 2 Duo - 80gb HD - Combo Drive - 1gb ram or 1.66 Core Duo - 80gb HD - SUPERDRIVE - 512mb ram I just pretty much know will the core 2 duo be wayy faster than just the core duo? thanks!
