I really want to buy a 2011 iMac and it's already annoying I can't use it as my monitor for my gaming PC. Now I can't even install an SSD without any problems like fan or temp issues for the HDD it comes with and the installed SSD. I want an SSD but not the SSD Apple uses.
I'm a long time custom PC user and those grudges you have with the iMac really took me awhile to look past. I built 3-4K custom PCs and used HP's 30 (ZR30W) for my screens. I dumped all of that for my new iMac. It was a big shock but I'm finding that I can be happy on an iMac. lol. My friends and business partners hardly believe it. Now they walk into my home office and they see an iMac, iPhone, and iPad2, and with these 3 devices I am more efficient running my business and enjoying more free time with my family. Over the weekend I was easily able to move my iMac upstairs to do some work while playing with the kids (wife was out of town), a luxury that I was not able to do with my custom PCs. As far as a monitor for gaming, you can use the 27" screen for gaming with an add on piece of hardware. I myself just use a 32 led sharp 1080p for ps3/apple tv and leave my iMac just for computer use.
