I fired it up today after installing the msata board. It took me a lot more than 90 seconds. I had to remove the entire fan assembly, disconnect the 12V power connector for the SSD before I could get the board out of the chassis. Roughly 10 minutes as I had to figure it out that first time. This is not as bad or as painful as the SC101-i case. I wasn't pleased when I discovered that the 60mm fan was chewing through the pico-psu that was right next to it.
I also took SPL measurements as I installed ESXi at 1m. Ambient office was 39DBa before powering up. It peaked at 61DBa and settled at 43.5DBa. All with the front of the case pointed at the SPL meter. The sides are mostly closed off, so I didn't bother to measure them. Rear of the case measured around 42DBa. I didn't take a peak measurement.
