Anyone convert their MAME Cabinet to JAMMA?

I have done it.

My cabinet was designed for MAME, Jamma, and a Sega Naomi. I do tend to use MAME more (even for the games I do have the PCB for), due to having a pause button (I'm always getting called away by someone, or have to use the restroom, or the phone, need a drink, ect.)

I'm at a point where I successfully (IMHO) made a MAME cab with a PC and TV, and am now looking to build/buy a cab for a functioning JAMMA board and arcade monitor... but I find myself anxious about the old (possibly irreplaceable) tech failing (even though I know a PC has more moving parts and is probably more likely to fail). How have you resolved this in your minds, or is it just part of the hobby?

I'm not too clear on what you mean by "older tech". The Jamma standard is just a bundle of of wires, a 56-pin connector, and a switching power supply. The PS is replaceable, since there a plenty of places you can get new ones these days.

The only "old tech" you really have to worry about is the Monitor and the actual game board itself.
And people have eliminated the monitor by wiring up an LCD monitor to Jamma instead, via a CGA/EGA/YUV to VGA Converter which up-converts the board's 15khz video signal to a 31khz one that an LCD monitor can display.
If you take care of your PCB's, store them properly, and make sure they're getting the proper juice from the Power Supply, they should last for a very long time (probably outliving your PC hardware).

Yeah, I guess I mean the PCB. I just see a bunch of components that I don't understand- but you're right, if I take care of it, I don't know why it would stop working. If it survived 10-15 years on location somewhere I can't imagine it would fail with home use.

BobA:
PCBs can always fail even with very little or no use.  Any electrolytic caps of the board can dry out over time and cause your board to malfunction.
