Well the most of the rig is in the new case. If it helps it’s the go 580-023w prebuilt. The motherboard is the odense2-k.I don't recognize this particular cabinet. You have more pictures to show a complete picture of this rig ?
I’m using the same motherboard. How do you think I could install the little things that are screwed in? Do they have to be screwed? Can they be inside of the case?Did you keep the same motherboard or are you using a different one.
The connectors in general are standard. If I remember correctly the ones that attach to a m2 type wifi card are a bit smaller than ones that connect to the older pcie type cards but the ones that say go to a m2 card will fit all m2 cards.
I assume the things on the outside of the case are the actual antenna?. They look kinda strange. If you can find a way to mount they they likely will work.
Antenna and cables are pretty cheap you might find a better option by buying something easier to install.
What would you recommend that I buy that would be easier to set up?From what I can tell those are grounded to the metal case. You don't want them inside because the case will block the signal. Best place is actually on top of the case where they are not blocked from any side but your current antenna won't work like that unless you build something to mount them to and the cables are likely too short.
If you want to use those antenna I would try to find some metal you can screw them into.
Okay. For the first one, does it plug into the PCI slot? Also, what is MHF4?This is a example what many people use

Key here is you need MHF4 on the end that connects the m2 card.
Now you can get fancy antenna that connect to this card that let you extend it away from the case.

On the second one I am not sure this comes with the metal plate you put in the back of the case. You can of course just run the wires out some hole if you want.
