I think TG sides are fine, though I am not a fan of it because I tend to open up my system to fiddle with the parts. So glass being glass is not as sturdy as a proper metal cover. Neither do I apply any RGB lighting in my system, so there is nothing to display. Machine & More's deshroud video did show that the TG glass of the NR200 actually help funnel air upwards, which improved the GPU temps quite a fair bit. I am waiting to see if that is the case for my deshroud mod. For my NR200,
Anyway, don't hold your breathe for my review of the case man. Nowadays, I don't have a lot of time to play around with my PC. So even things like swapping out fans can take days or even weeks.
But I have to say, I am quite excited to try it out. I've just measured the bottom fan distance to the second PCI slot, and I think it is possible that the 30mm thickness of the T30 may just fit in nicely with no gaps. It may even be fatter by a couple of mm.
I opted for this case because I think the ability to use a ATX PSU and to install 2x radiator are going to be useful in the longer run. The NR200 is quite limited particularly when it comes to installation of radiator. My poor Arctic Liquid Freezer AIO's hoses are getting bent out of shape in the case as well because of the extremely tight fit.
