Question

Iron

Good afternoon. Nowhere can I find the dimensions of a standard motherboard and video card (including those with a plate, where are the connectors). In other words, how should the slots in the computer case be located, into which the back panel with the motherboard connectors (adapter plate that comes with the motherboard) and the holes for the video card will go? Regarding the mounting holes of the motherboard.

In the system unit, there is only one such slot, large and rectangular. The bar with slots for MP connectors is unique for each model and comes with the motherboard.
