Opening up the top panel, you get a view of the interior. Notice the lack of fans. This is a passively cooled system and therefore almost completely silent. Cryo PC purportedly undervolted (but didn’t underclock) the system in order to achieve this. Cables are well managed keeping airflow channels clear and making customising of the system easier.
The SSD is tucked away in the corner drive bay. There’s also space for two other drives there if you want to increase the storage capacity of your HTPC, but they wouldn’t have the quick-swap ability of the Seagate drive shown earlier.
