Long time lurker here... Finally felt the urge to join and share my project.
I have been planning this cabinet for about 6 months, working on it for about 4 weeks. I probably have about 16 hours or so in the construction, and am almost done with the woodwork part
A few specs:
17" pc monitor from a college auction. Turned out to be a trinitron.
AMD 1.8 with 256mg ram, and 80gig HD. Computer was free from work (DVD,CDRW,floppy,video card included) had a dead MB. Paid $27 for a new MB, and actually got paid $20 to buy the HD after rebates. Computer cost = $7

I-PAC for inputs
All wico leaf sticks. (2) 8-ways for Robotron, and a 4-way for LOML to play Ms Pac Man.
Bob Roberts took care of the rest, except coin up buttons and start buttons will be radio shack mini buttons to save some space.
Cabinet is built at 3/4 scale from Jakobuds Pac Man plans, but 22" wide inside to allow for the 8-ways. It is sized so my 5 year old can stand and play, and I can sit and play.
Used 5/8" MDF and 3/4" MDO for construction. NO fasteners through the sides! It was a goal of mine to not have any patching to do on this. My primary hobby is woodworking so I went the dado and glue-joint method, and am very pleased with the results. The joints ended up nice and tight, with good adhesion. The cabinet is "strong as bull".
I'll just let the pics speak for the rest. Let me know what you think!
