I recently bought this case for my build:
GTX 1070Ti
i7 9700k (Corsair H100 v2 water cooler)
I’m not planning to OC anything, will the temperature be ok? I’ve heard the airflow is pretty bad, I was wondering if things could get bad.
 
Solution
Can you return/replace it? If you can then there is this thermaltake with similar specs which I have been thinking about for myself. Has grilled front with dust filter so no concerns about airflow.

If you can't then personally I would look into seeing if you can't remove that acrylic panel at the front and remount it again but with a spacer so it is further out so it lets more air in around the sides. I am sure that would probably be enough to keep the case cool... may not look quite so nice with the front sticking out further, but if you search your local DIY store you should be able to find some kind...
If you've already got it why not simply test it to find out? Depends on your situation as well, where I live ambient temps hit 40 in summer... tbh given what you have said I would be surprised if you have a major problem...
 


Everyone is saying that it’s really bad so I just wanted a clear answer, all the negative review of this case scared me pretty hard.

Edit: I bought it online so it’s on its way, that’s why I’m so concerned about it.
 
airflow on water coolers is mainly determined by the fans. Fans with high static pressure work well with radiators, phanteks makes some nice fans with good static pressure, i recommend taking a look at them

Its hard to tell from photos how that acrylic plate is attached. But with a little care and creativity I would have thought you could do something reasonable... depends whether you are confident doing that. I know it isn't attached the same but this guy came up with a similar solution to a Walmart gaming PC here:

Solution


I saw a video that a guy just attached the middle plastic thing that attaches the acrylic plate to the rest of the case. It’s actually not that bad, since aesthetics is not my concern as I will have change the rgb Fans with the liquid cooler ones anyway.
 


Cool, if you have the confidence to do it and are careful and methodical I reckon you could do a perfectly decent mod on that case very cheaply.

Good Luck!
