First, I agree with what you're saying about Louqe sticking to their guns. It's great to listen to community feedback, but it also instills confidence in consumers if you have a vision for your product that you're seeking to execute. Everyone who is making comments about increasing the width hasn't participated in the discussions here that explain why it's not worth it.
Here is an
Imgur album with captions that explains the issue. Basically, because of one of the motherboard heatsinks near the IO, I can only orient the cooler east-west and not north-south. If the heatsinks run towards the PCIe slot, they stick out too far and obstruct it. If I run them the opposite direction, the poke past the edge of the motherboard. This might actually be OK in some cases, but for the SG13 there is not enough room and it would be impossible to put the cover on the case. The RAM clearance appears to be the 43 mm as stated by Louqe in their test.
Edit: This is not an issue for the Ghost S1 as the use of the riser means that obstruction of the PCIe slot doesn't matter. Just wanted to give a heads up to anyone building a test system early.
