Pointless question for pointless ports

[MaxwellArchitecture]

I've gotten myself an old server case with loads of 5.25 inch bays, and I plan to (using many adapter cables and internal USB hubs) build a modern pc in it that can take pretty much any accessory or storage medium ever made and use it. I've already got floppy to usb adapters lined up, as well as plans for modding a cover plate for the somewhat odd dual psu mount, but one thing I haven't been able to find is what to put on the serial/parallel port covers on the top right:

(note; not actually mine, but the same model; mine doesn't have the plate for two psu's, is black, and does have an IO plate)

 

From some googling I've found out they're called 'knockout plates' or something like that, but I'm looking to fill them all up with appropriate ports and adapt them to usb somehow so I can use them in a modern rig. Any suggestions?

It could be possible to put a GPU in there, although I'm not sure how good ventilation will be

I've already got 7 slots, I don't think I really need more. Besides, I wanted to use them as intended.

If all you're wanting to do is fill them with what was originally designed to go there then it's pretty easy. The ones with the "plus sign" shaped holes are designed to that you put the tip of a screwdriver in the hole and "kock out" the tab covering the hole. The other 2 ports look like they have screws holding in cover plates and should be easy to remove. If you need help figuring out what the ports are for I believe the 2 on the right are db-9 serial com ports. The 2 in the middle look like they could be db-25 parallel ports, and the 2 on the left look like they could be SCSI ports (possibly sca 68 or sca 80).  These are all guesses based on one photo so take them for what they are. hopefully if I am wrong someone will correct me.

In the old days they are mostly used for serial and parallel ports, where you can just secure them there instead of wasting a precious I/O slot, since those ports are just connect to the board with a ribbon cable.

I think I get what I'm supposed to do with them, I'm just having trouble finding the cables with connectors to place in them

My point was to not use up any pcie slot as well, so unless I intend to invite the angle grinder man over I don't think I'll buy something like this
