Building a head 2 head box.

I wrote Chin Music EX to make any game playable head to head on a cabinet. I've decided to go the next step and make my own head to head arcade box.

I already have a 20 inch computer screen I haven't been using with integrated speakers. So that's a big part of the expenses.

Here is my projected parts list.

Motherboard CPU Combo
http://www.amazon.com/gp/product/B0041RSC94
 $75.25

The Dual Core Atom and the 3150 should be more than adequate for emulating most consoles and has good drivers for Linux should I choose to go down that route later.

RAM (4 gb)
http://www.amazon.com/Crucial-CT25664BC1067-204-PIN-PC3-8500-SODIMM/dp/B001KB6Z2U
2 x $12.99 = ~ $26

4 gb of ram should be way more than enough for emulating anything I want.

Controllers x2
http://www.amazon.com/Retro-Sega-Saturn-Classic-Controller-Pc/dp/B003KMWMYW/
2x 6.56 = ~ $14

I will be tearing these apart to get at the control boards. This tutorial here should get me on the right track.

I am still giving strong consideration to making the control panels modular, so you can pop off the controllers and play side by side in addition to head to head.

Buttons and Sticks x14, x2
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=380222939700#ht_3199wt_1270
$40.00

I might get a few extra buttons in the future, but this should be more then plenty for the moment.

Pico 12 volt PSU (90 watt) + 12 volt PSU
http://www.amazon.com/PicoPSU-90-90W-12V-DC-DC-mini-ITX/dp/B00316RGD4/ref=sr_1_20?s=electronics&ie=UTF8&qid=1315934137&sr=1-20

http://www.amazon.com/Kinamax-AD-LCD12-Monitors-Adapter-Supply/dp/B000VE7GQQ/ref=pd_bxgy_pc_text_b

$31.00 + 9.19 = ~$40.00

90 watts should be more than enough for my needs. This machine won't have a DVD drive, or anything like that. I don't want any fans either if I don't need them. Also only has the bare minimum of wires.

Non-construction parts cost:  ~195.25

After I take some measurements, I will post about the actual construction costs.
