Hey guys…I'm a noob, trying to install a MAME system on an Arcade Legends 2 cabinet. 25" CRT

I have a Dell OPTIPLEX 990 that came with it…nothing installed. I'm good with PCs but man, I'm feeling really out of my depth here.

Anyone else have a MAME setup w Dell OPTIPLEX 990 using onboard graphics and a CRT, I'd sure appreciate some suggestions.

Question: In addition to the old classics, eventually I'd like to install stuff like PS4 games like Injustice2, etc…is that just not doable with a CRT?

Thanks guys…and looking forward to learning my new hobby!
