I always take a photo of my rebates filled out with UPC taped and paperclipped and include it. Never had a problem for my ~15 I've sent in.I'd just like to warn everyone in here that MSI are scam artists when it comes to rebates.
Here's a few links that echo what I'm currently dealing with:

Here's a log of my experience.
Doubt this is exclusive to MSI, the rebate companies just will try and screw over anyone they can. FWIW most things I've sent in have been with 4MYREBATE.
It's just a lot smaller, which I find nice. Being able to fit all of that in there now is neat and thermals aren't a real big deal anymore, plus you can have a water cooler in there to boot.Are they considered better or just as good for airflow? It would seem at first glance that being smaller like that might mean it gets hotter in there quicker, but what the heck do I know. Sorry for the dumb questions. All of this is just new to me haha.
