If I were to build a new gaming pc...

I really only have one quick question on this subject matter. Is it possible to use my iMac's gorgeous monitor as a monitor for a windows machine? I absolutely love my Mac, and it's plan was to be utilized as a "family pc". Movies, music, and actually alot of gaming has been done on it! I would just love to be able to plop a gaming windows machine down below the desk and use the iMac's monitor with it. That beautiful screen would make me happy! It has a thunderbolt connection. Is that already an option? Maybe down the road?

You'll likely have to use an adapter.

Any downside to that?

I'm not an expert, but I wouldn't think so.  Signals are digital, so they get there or they don't.  It's not like you run into issues with static. 

And it seems like Monoprice can get you covered for pretty cheap.

It depends on the model. Some iMacs have the ability to accept video input and others do not. For instance, when I bought one for my daughter awhile back, I was told that this was not possible on the 24", but was on the 27" (Of that particular revision...may not apply to a different one).

A lot more video cards have display port out now.  In that case if the iMac takes display port in you just need a standard dp to mini dp cable.
