Thanks for the input. Before I installed the vertical mount I had viewed a few YouTube channels that tested the vertical vs traditional mount. The difference didn't seem very significant to me so I proceeded. If I was more into competitive benchmarking I would not have installed vertically in my case.I dislike vertical mounts in standard cases. They might 'look cool' but generally are just the opposite, since most atx cases do not have the depth to handle the airflow restrictiveness of the sideways card being right up next to the glass.
Vertical mounts are generally far better off when incorporated into a full custom loop, even most hybrid/aio designs use a gpu mounted fan for vrm/vram cooling.
Sounds like you are very happy with your case. Great work.$180 for a massive case, that adds a huge amount of real-estate on the desktop, just to maintain a vertical gpu isn't what I call a 'slight compromise'. That case is 2 feet tall, almost 2 feet deep and 10 inches wide. That's a ton of air volume to move and nothing in the case worth mentioning other than the gpu. Those E-ATX full towers are designed for massive storage potential like Nas etc.
I just see it creating more issues than solving.
My case is just under 12litres. A standard 120mm 50cfm fan has no issues expediting the removal and replacement of 12litres of air volume. Your standard ATX case is roughly 44litres. Pretty close to 4x the volume, and really needs 2x intakes, 2x exhaust to keep decent airflow. The Define R7 Xl comes in closer to 84litres, and with nothing inside to absorb the airspace, just a gpu, you can expect some not so nice temps.
Bigger and does not necessarily mean better.
Thanks for the information. I think I will wait for the RTX 3090 release on Tuesday and decide what I want to do at that time.It's an amazing case.
Size 10 shoebox, and those aren't high-tops. It's small enough that it doesn't even need case fans.
I also have a Define R5 Window, basically the R6 twin. So I do understand it's limitations. There are other options, Lian-Li makes adapters to fit several of their cases. Like this one.
The R5/R6 is limited by what the manufacturer has specd for the case, that's not to say every manufacturer is the same, it's why they call them case mods. A manufacturer might say only 3 fans fit, 2in and one rear, but what's to stop you from zip-tie a fan to the hdd cage?
You can put a 3 slot gpu vertical, but not if only using the case as designed.
