I worked all day on this bad boy. I've got the monitor brackets installed where they actually fit the monitor mounting holes (hey how 'bout that?). \
I was able to successfully install the GT FORE COMPLETE upgrade. This entailed changing a security chip on the PCB, hooking up a CD-ROM drive to the motherboard, connecting the on-board modem to a landline, and running the install program off the CD. First two times failed due to an incompatible CD-ROM drive. I attached a different drive and it worked lickety-split.
I installed the PCB, hard drive, and power supply into the cabinet. I installed the power surge protector and marquee. Due to the incorrect plan measurements I had to do some creative rigging to make the marquee look good, and it looks great now. The speaker is connected to the PCB and I have play tested the controls with the monitor on the floor. Tomorrow (later today, actually) I have to unscrew the screws holding the monitor brackets and replace them with 1/4-20 bolts that go completely through the sides. If I can catch my dad during his lunch break I'll get him to help me mount the monitor.
Should be complete with everything but the speaker grill and bezel by tonight. If I can catch Steve after work, I'll get the monitor bezel installed as well.
I'll post detailed photographs on the monitor installation using DrewKaree's bracket mounting method when the cabinet is finished. I highly suspect I may get delayed a day or two if I get started playing this sucker again.
