Recommendations for upgrading RAM in iMac 27

Sorry if this post should be placed somewhere else or if the answer has already been posted a bunch of times on threads I'm not finding with my search. . . just joined the forum and don't want to be "that guy". . .

So I'm about to pull the trigger on a new iMac 27. I'm thinking a beast of a computer like this going to need all the memory I can give it so I'm wanting to upgrade to at least 8-12 gigs and see how it runs. Obviously Apple would love for me to go ahead and have them install is for the low-low price of $200-$600. I've never installed a RAM on a Mac (this will be my first) but I've installed plenty in PCs. Is there any reason not to go with a set of dimms from Crucial or Kensington in terms of performance? 8GB of memory can be had from Crucial for $45. And I've heard there's 4 slot in the iMac 27, so I'd end up with 2x2 + 2x4 = 12 for about $50. Would that be a tremendous mistake? Am I fooling myself to think I'd be able to install these myself?

Thanks in advance for your help everyone. Like I said, this will be my first Mac, and I'm really looking forward to learning how to get the most out of it on this forum!

Installing Ram in the new iMacs is incredibly easy to do yourself. If you've done it in PC's before, you can do it in your iMac.

The ram from Crucial sounds good as well.

Here you go, really quite straightforward:

Just make sure you use the Crucial scanner to identify which spec of ram you need.

Thanks for the input. Sounds like the non-apple memory will be a snap. Can't wait to immerse myself in the new system!
