I have an msi a78m-e35. I tried to install a network card but it wasnt filling in the slot. only once i returned it is when i realized that the little par thing is on the other side of the slot, would anything go wrong if i put it with the antennaes facing inside the case?

This motherboard has three expansion slots. The top (blue) slot is the PCI-Ex16 slot for your graphics card. The next one down (shortest), is your PCI-Ex1 slot. This is the slot typically used for network/wireless/sound cards these days. The bottom (last) slot is a old standard PCI slot which is not compatible with any PCI-E card.

PCI-e slots are visually backwards from (older) PCI slots, and the spacing of each contact on the connector is larger on the (older) PCI port. the PCI port is also taller and more blocky.

it's not a PCI-e slot. it's a PCI slot. and no you can't plug a PCI-e device into a PCI slot "backwards" and expect anything to work.

If your network card is PCI and you're trying to plug it into the bottom slot, then you can't turn it around and expect it to work. PCI slots come in two different voltages - 3.3V and 5V, and the position of the divider in the slot determines which type it is. If the divider is on the right end (towards the middle of the board) then it is a 5V slot, whereas if the divider is on the left end (towards the board edge) then it is a 3.3V slot.

If your PCI card has only one notch then you have to match it to the correct slot in order to install it. Many PCI cards are dual voltage, with notches at both ends of the connector, and will work in either type of slot, but some cards only operate at one voltage.
