So, whats the damage? Here are the various costs. I want to be clear that I set out to make something similar to those "commercial" cabs that people are making. I also want to play newer lightgun games at 1440p and higher.
The reason I am putting the costs here is because I know a lot of people are probably seeing these on Youtube and also see how much is being charged. Well, here is what it costs me in parts. I had all the tools already so no pricing on things like that. Keep in mind that I also use a lot nicer hardware than those cabinet builders, especially the display. The structure itself is of better materials as well. You can look at components that I used and determine where costs can be saved.
For example, you can get a TV display for half the price. I did not want to cut a hole for a remote IR sensor, and also I wanted g-sync at 4k. So I chose a screen that uses wireless tech for the remote and also supports a 120hz refresh rate without screen tearing. It's a gaming display and I have zero regrets on it.
You also don't need an acrylic bezel. I personally love the sheen and look. You can just use hardboard and cut a hole in it for the screen, which runs around $20 for a 4x8' sheet.
Finally, the GUN4IR lightgun costs are not included either. I hacked up arcade guns which cost me about 300$ each total. But you can mod toy guns for like $40 if you want basic guns.
