That is awesome
nothing way to expensive either.
seems like a great deal. If you had to say (and if you don't mind me asking) what do you think your total cost was?

I don't mind at all. Here's the breakdown:
PC Specs
$50 Mobo: Biostar K8M800 Micro Motherboard - Via K8M800, Socket AM2, MicroATX, Audio, Video, AGP 8xk ...
$60 CPU: AMD Athlon 64 X2 4600+ Processor 2.40GHz, 1MB Cache, 1000MHz (2000 MT/s) FSB, Brisbane, Dual-Core, Retail, Socket AM2, Processor with Fan
$36 Memory: 2GB (2x Patriot Signature 1024MB PC5400 DDR2 667MHz Memory or similar brand)
$25 Video Card: PNY/Nvidia 256MB FX5200 PCI w/ dual VGA outputs
$200 Monitor: Hannspree HF-259HPB 24.6" Widescreen LCD HD Monitor - 1080p, 1920x1080, 16:9, 1000:1 Native, 3000: Dynamic, 2ms, 60Hz, Integrated Speakers, VGA, HDMI
$--- Backglass monitor: unknown, about 19"
$100 IPAC2 (which in hindsight I didn't really need, I have a spare gamepad I could've hacked but oh well)
$22 Altec Lansing Speakers w/ sub from office depot
$10 Logitech keyboard
$--- optical mouse
Note that most of the ocmponents I already had laying around. The only things I bought specifically for this build were the playfield monitor, the 256 MB video card, and one of the GB's of memory. But I included the original prices I paid back when I got the
other components as well.
So, about $770, assuming 170 for the backglass monitor and an $8 mouse. Luckily I got the bg monitor for free from
good ol' mom...
Build-wise, all the wood was free or leftover from other projects. Literally, some of it came from an old computer
desk my neighbors threw out. I think i did have to buy some wood screws and glue, and two $1 picture frames to use as speaker hole covers.
