Hey guys, I currently have a 13" 2011 Macbook Pro (Lion) and a Dell XPS 8100 desktop (Windows 7). I want to have a machine act as a server in my home so I can VPN and FTP to it from any internet connection. However, I'm not sure either of these machines are suitable for that task ... Laptop for battery reasons (maybe?) and Desktop for power consumption reasons (insignificant?) For this reason I was considering a low power option like the Mini ... But if I buy the Mini then my desktop has to go (depending how much I get for it) ... I cannot justify owning both of them as I am not rich. Specifications of the Dell XPS 8100: Quad core i7-860 2.8GHz (Lynnfield) 2 x 1TB SATA II (RAID 0) 8GB 1600Mhz RAM ATI Radeon 5770 HD Blu-Ray ROM/DVD Writer DVD Writer 19 in 1 Media Card Reader ... Regardless of which Mini I choose, it's a step down in specifications, but the important thing is I don't need all that power. Most tasking thing I do is Adobe Photoshop CS5, Adobe Lightroom 3, and Civilization V. What would you do in my shoes? I believe the Dell has a ~500W PSU, leaving this on 24/7 compared to the 85W PSU ... Is it really significant? Should I just invest my time in setting up the server on my Windows computer? Will setting it up on OS X make the server less vulnerable to breaches? Please advise. Thank you!
