Hello Nick, A a warm welcome.. great 1st post too!
I'm afraid using the iMac for a PC Monitor is out, unless it might be a newer PC that has a thunderbolt prt & can output Video through TB port. 2009/2010 iMacs can use MDP. But 21.5" iMacs work as well as the 27" ones for either method.
Not sure DVI or even DisplayPort converters work though.
Here's how it's supposed to work...
Mid 2011s & up need Thunderbolt!
Are 8GB of RAM really necessary for Xcode, and is the quad-core CPU of the iMac needed?
Well, problem is twofold, 4 GB is barely enough for the OS & one App, & you can't really upgrade the RAM yourself later.
I'd go for the Quad core, computers always get slower over time!
Might be some 209/2010 options here...
I was afraid of that.
Thank you so much for your help!
I just wish I could install a Thunderbolt bay into my PC. (Searched NewEgg, nothing.)
Do you the 27" Retina is worth the extra $500?
Just one more question:
Can Macs make $1700 appear out of thin air?
Hi to follow on from the initial question, you mention that 4gb is barely enough for the OS and an app. As this will be used for app developing is it advisable then to skip the mini completely as in order to get to 16gb it's pushing almost the same cost. I've also heard rumours that the mini doesn't perform well with a DVI adapter when using a stock pc screen which is where i would save space by using the same monitor for a windows based PC as well as the mac but I don't know how true this is.
Any advice? Thanks.
