They look great!! nice job.
I started working on my 6 aethers today. I'm doing them all at once and it is going quickly. Like you, my first ones took a while, mostly with programming, debugging, and some time trying to get a fit with heat sinks and cases.
The aethers from last year were really my first kit, an i'm surprised how my skills have improved in that year.
I had my son paint my cases in prep for this build. yours look very nice (in comparison
)
