Just for the record, if you are going to run anything modern on a cab, you go with an lcd.... it isn't much of a debate at this point. Modern games are designed with a 16:9 ratio in mind and crts are incredibly heavy, bulky and require specialized hardware to interface with a pc. On the other hand lcds small form factor allows you to put then in any configuration and with modern video cards having a native hdmi out, you can just throw a budget tv in a rig and get a hd picture right out of the box.
I was very adamant about crt only back in the day and if you are restoring a classic cab (pre mid-90's) then it's certainly the preferred method. However, if you are making a mame cab, again unless you are going to be playing only classics on the thing, it's just more practical to use a lcd panel, especially now that mame and other emulators have hlsl effects that do a good approximation of a crt.
It isn't even something to argue about anymore. Even happ primarily sells lcd replacements for monitors at this point. If you prefer crt displays then that's great and you should use them... I have a few in my classic cabs, but justifying using one in a new build is getting harder and harder as the years roll on.
