That is nice! Those 3 fans provide enough airflow when it's all closed up and in a rack?
Are you making those to sell? How much did it cost you?
It's too early to tell, but it looks like airflow is enough.
I'll know more when I'll have 10 cases in one bay

Prototyping is very expensive, but I plan to make 100 pieces so at then end it should cost ~150.
I'm not doing it primilary to sell, I have the need to build clean cases for data center hosting.
If you are really interested I could sell of course, but international shipping would be quite expensive (I'm in France).

Nice work Eric - I work in a datacenter, and having professional looking machines in our racks is very important. Best of luck to you!
