Accessories for the new Mac Pro design?

I have had this thing for almost two years now and I love it except for the ports in the back.
They constantly wiggle loose.
Are there any accessories I can buy to make sure all cables are locked in?

Thanks!

I have tons of cables in mine, and they never work loose. Are these cables you plug and unplug often? Make sure they're all the way in, and they should be pretty secure. What are you moving around so much, that cables are wiggling?

The back of yours is the front of mine. What I've learned is don't move the Mac around and have plenty of slack at the Mac end of each cable.
I use:
4 x USB
3 x Thunderbolt
1 x Ethernet
1 x headphone
1 x mic (sometimes)
1 x HDMI (gets plugged and unplugged ten times a week)

How are you able to plug a mic in a 2013 Mac Pro? I thought those were both headphone jacks. I've plugged mics into both jacks and neither were recognized by the system. Or is it iPhone mics that the system is looking for?

By the way the cables attached to my Mac Pro never come loose and I'm sure I use every single jack (and it's still not enough, need two Pluggable 7-port USB 3 hubs).

Again, I have lots of cables, none ever "wiggle" loose. Nothing wiggles. How does a cable wiggle?

It doesn't really wiggle. But gravity likes to grab hold of my cables and yank them out. There aren't any screws to hold them in place like a VGA cable, DVI cable. I have every port filled and a 6x USB hub. And there still aren't enough ports.
And the way I have to sometimes find the power button, the mac does sometimes move. The power button really should be on the front imho.

I'm filled with cables, and don't have that issue. But, I don't hang my cables off the edge of the desk, they rest on the desk.

My apologies. A headset mic is attached to one of those cute little Griffin Mic units via USB. sue it for rough voice overs and the occasional FaceTime or conference. Come to think of it, I never use the old Harmon Kardon speakers attached to the speaker output since we got the HDMI working predictably; it sends image and sound from FCPX to a monster TV for client showings. Since my partner is within spitting distance, we've been using our headphones for many years now to work on our individual projects.

The cylinder rarely moves.

Speaking of USB, I use all four USB ports on the cylinder plus three more from the back of thunderbolt displays. 2xLightning (iPhone and iPad), 1xd (small thin for weird portable battery packsand the odd portable drive), 2xC (large polarized for Nikons), 2xUSB regular (for the Panasonics and my bicycle lights). I've got USB cables all over the place. And a DVD burner. And the iMic. Guess that's 9.
