I'm looking forward to seeing the results!
I built one 18 years ago. Its still going strong. This 65" monitor idea is interesting I may need to consider an upgrade. I had a Betson CRT monitor but it conked out years ago. Now use a widescreen monitor, the 4:3 is a much better idea.
If you need any pointers let me know. I've upgraded mine lots over the years, and am now considering installing an up/down spinner to replace the two way spinner. My Ipac4 is still going strong.
My controller is pretty close to this:

Has dual rotary joysticks (2 joysticks per player, left one a rotary, right one a joystick with top shoot button), spinner, trackball, central top joystick is a 360 for games like sinistar. Have 2 guns too.
The most popular game when friends are over is easily Shuffleshot. Check it out. We usually play for a buck per player per game. Cheap and fun.
