Even if the XL version offers more space for disks and fans, the basic version is sufficient for my installation which includes 2 SSDs + 1 SSD.M2 and 2 watercoolings.

I don't recommend it if you have an E-atx motherboard 0 place 2 rad 360 impossible and the cables I don't even talk about it

It depends on the size of the motherboard and the cooling requirements. I have a 360mm atx and 2 rad motherboard, that's more than enough for me to keep my fluid below 30°C with an overclocked 1080ti and 9770K. And I can have the tower on the desk because of its reasonable size. Not sure if that's the case with the xl.

It's great but I've had a little problem with it:
I have an E-ATX motherboard and there is not much room left to run the MB power cable between it and the fans.
I'm not going to change it any time soon.

Hello,
I bought the 2 for atx I advise the normal and for an e-atx card the XL version, both have enough space to put a good watercooling.

We ordered this version, as it is sufficient for our professional needs (2 GPUs installations). It all depends on the use.

For me this version is enough, I recommend this one. Look at my review, there is a picture.
