It's a seenda (I like them better than apple mice and they're cheaper as well), but I get your gist. Some people hate that style, but I dig it.
Temps and performance are both good. Idles silently at 35-40 C and with fan RPMs of 0-600.
Hours of benchmarking and gaming haven't led to any heat issues so far. I plan to run the superposition benchmark for a few hours this weekend as well.
That's why I kept track of 100% of the components!
I wondered about airflow at first too, but it seems to be sufficient.
The top of the drawer is closed with acrylic (that's where the power switch is mounted).
I want to keep it simple and avoid over-engineering. Right now one intake and one exhaust fan seems to be performing well. If airflow issues pop up, the next thing I'd do is install another intake on the other side to increase the internal air pressure.
