This one was mounted in a Lian-Li PC-Q07 mini-ITX tower case. It works with the picoPSU 120 and acts as a mount for the picoPSU's power jack (where the AC adapter plugs into the DC PSU). Since the PC-Q07 has no fans, the plate also has a mount for an 80mm fan making this the one and only case fan for the PC. It also performs the job of plugging up the ATX opening where a full-sized PSU would normally be mounted making the PC look better too.
This is the front view.
