Okay, thank you all you have been very helpful. It is much appreciated.
I kid you not when I say that they since yesterday updated the product page of the built variant I'm looking at which means it now features a Gigabyte Z68AP-D3 motherboard instead of the Gigabyte PH67 motherboard. So I guess that's all good and ready for all the overclocking I'd either like or don't like to do, yes?

The processors they show are still the i7-2600 and i5-2500 but I'll ask them about the i5-2500k. I'll find a good monitor that fits my needs and then I'll decide upon the graphics card.
Thanks a ton!
Edit: A quick yes/no: We are in agreement that an i5-2500 is just as powerful as a not overclocked i5-2500k, right?
