I preordered 4 days ago the NCase M1. This case costs the same as it will cost me to import the M1 (I can get the H1 for 290 and the M1 will cost me 280 euros at least), and also includes a PSU and an AIO, so the price is way better in the NZXT.
In addition, I have a lot of vertical space, but little horizontal, so a vertically oriented SFF case is ideal for me.
Could you convince me to keep the M1 and not cancel it for the H1?
Positives of the M1:
* 3x 2.5" (less likely to use all 3 + m.2, but on my current desktop I have 8 HDDs)
* 240mm AIO support (seeing the CPU temps in the H1 I'm not too worried about the AIO, but still 240 is better)
* Greater GPU compatibility
* Aluminium / build quality
* best temps in the SFF market
* no PCie riser - less chance of black screens / points of failure
Positives of the H1:
* looks
* space on the desk
* cost
* CPU temps are good enough (lower does not offer much advantage except HW longevity)
* GPU temps are ok-ish, I was expecting way worse (Evolv Shift anyone?), and I won't put in anything over the TDP of a 2070 Super, with undervolting I believe it's going to perform fine
Honestly I really want to get the H1, but I don't know enough about SFF (this will be my first SFF build) to estimate which case will be best. I'm planning a build with a 3800X or 3950X, and a 2070 Super or equivalent (maybe ampere by the time the case arrives), so not the highest TDP possible. Money is not an issue, but lower is always better

My heavy workloads will be gaming, and software dev (so at worst a few docker instances, and IDE and many many browser tabs), given that, CPU and GPU will never be stressed at the same time, so thermals will be less of an issue.
