Bouncing PC! How to secure PCI/PCIe cards and keep cables in place?

I have a desktop PC with a lot of components including a large number of PCI/PCIe cards.

The problem I have is that the machine is regularly transported long distances by a variety of means, including rail, road and sea. What happens is that the (often quite generous) jars and jolts of the journey cause cables to fall out and cards to rise out of their slots at the unsecured end.

Each time I have to open everything up and reseat everything. If the machine arrives somewhere where I'm not, it can't be used until I arrive.

I've gotten around the problem of SATA cables falling out by purchasing cables that clip into place rather than just flap about in the usual fashion. What I don't know how to do is secure ribbon cables, audio cables, cards and the like.  Because of various constraints:

- I can't use plastic zip ties (there's nowhere to secure them)
- I can't use brackets (the cards are half height)
- I can't swap out or modify the chassis

The only option appears to be glue. Old fashioned sticky stuff.

Thing is, I've read an awful lot of things on the web and while this question gets asked a fair amount there is no consensus. Some people say to use a conducting type (which seems plain idiotic, given that if applied to a PCI interface it'll short out), and others say to use a glue gun (which might introduce problems with regard to the heat and chemicals).

The only suggestion that made sense was a silicon sealant from Loctite designed specifically for circuit boards - Tempflex - but there's almost no information about it and the word 'Temp' makes me concerned it's just a makeshift solution (no pun intended). It's also really too expensive to buy a tube and only then discover it won't work.

Does anyone have any thoughts?

.  A dab of hot glue will secure most of your connectors and maybe the cards, also.

an antistatic bag because they can be heatshrunk closed and fill it with expanding spray foam, and make sure the bag is big enough to fill the whole computer,
Insert the bag then fill with foam. close it up and you will have a form fitted packaging for the inside of the computer

Use silicone sealant if it gets treated this roughly.
