I like this case, and complaints about airflow are overblown, in my opinion. You should certainly add more fans than the one it comes with.

But, it's a cheap case, and sometimes there are problems. You better check it out as soon as you get it and make sure everything works. Because you are SOL once you submit that rebate. (Assuming you remember to submit the rebate, and do it perfectly)

Remember when these cases were selling for $150 each? lol Built 3 pcs with this case. I only recommend it if you're on a super tight budget. Mounting points for fans are a pain to find. Protip: Plug the 8pin into the mobo before mounting it on the case or else you're gonna have a bad time trying to plug it in later. Great thing about this case is the airflow and feet on the side if you want to lay the case sideways for some reason.

I did it perfectly, but still got my rebate denied for some strange reason (forgot what it was).its 10 bucks, i didnt bother to contest it.

I got 2 of these cases about 3-4 months apart. its pretty basic but functional.. simple lines and minimalistic look. i use it without the magnetic filters, looks better that way imho. the thing that makes these cases special is that you can make some minor adjustments and flip the case upside down in case you need a right-side window.

I got this last time it was on sale. I bought it knowing I wouldn't submit rebate. No one has time for that. It's roomy for a micro-atx. I can't do ssf anymore too cramped!

Same here. I think it's because the box didn't have a UPC. I sent in all the barcode i could find on the box, rebate still denied.
