My IPC-PP827 board arrived. It seems the network ports and keyboard will power, but there is no display output or POST beep. Maybe I need to connect something to the power connector?
IPC-PP827 seems to be a rebranded version of PCI-827LF from Protech. In fact, it appears that all of the products on Ant Computer are rebranded Protech products.
Protech has a habit of removing manuals for older products, so I probably can't find the manual for the PCI-827LF (only the datasheet). However, the product catalog specifies the same P8/P9 to 10-Pin power (27-012-02501071) for multiple products, which contain the pinouts for the power connector:

Maybe I can stick two pins of the four pin power into pins 4 and 5 of the connector?
The manual of the PCI-586HVE-S seems to follow the same layout of the aforementioned manuals. Maybe Protech manufactured the PCI-586HVE-S too?
Also, my USB bracket arrived. The connector didn't fit since it was too small. However, I have the pinouts, so I can make my own cable later.
I was going to install a gigabit ethernet card, but I got a wrong PCI card (a SPIDF in/out card instead of a dual gigabit ethernet card), so the seller is sending me the right one.
