You mentioned lighting the JS, indicating whether it is a 4 / 8 way game. You could do this by inlaying Plexiglas in the CP. I recently picked up a bunch of various diameter round Plexiglas stock to play with for a similar application. It comes in 1/8" diameter increments.
Good luck on your project & welcome to the forum.

Thanks for your input theCoder, I have seen your thread before and you are doing some awesome work. There is plenty of info that will be of great use to me.
I like your plexiglass idea but I think i know how im going to mount the LEDS, actually whilst typing this sentance I have had an idea which will incorperate my idea and yours, thanks!
Thanks for the welcome too, I have been around for a couple of years tho - Ive just been in hiding! :)

Thanks for the advice too. Ive decided against the 270, I dont want to run the risk of overheating plus it will be hard to upgrade in regards to video etc. Not to worry though, the same guy has offered me a 3.1Ghz Dimension 4600 with 2GB DDR for the same price! (£75) :D It means I will have to decase but that isnt a problem.
Wooo, im getting really excited about this project now :D Im going to stay in tonight and carry on with some CAD with help from mans best friend (the cold, fizzy kind) and I hope to get some preliminary designs up later on.
Thanks again all, watch this space....

Be mindful of airflow, whether you decase or not. In most modern cases, airflow is designed to pass over heat-sensitive devices. Decasing and randomly placed fans do not, by themselves, guarantee heat dissipation; make sure airflow actually passes over your components...
Franco:
This has been taken in mind. The original motherboard has a 90 degree bend tunnel which draws air directly onto the CPU. I cannot easily recreate such direct airflow towards the CPU/motherboard but my plan is to posistion the fans so that they provide as much airflow as possible towards the CPU/motherboard.
Im still undecided whether to have four fans pulling in air around the CPU/monitor and have enough ventilation at the top of the enclosure to release the air or should I have two fans pulling air in around the CPU etc (at the bottom) and then have two fans to expel the air at the top. Any thoughts?
By the way the design is coming along a treat, its just taking longer than I expected it to.

:D
EDIT: I seem to have noticed some kind or relationship between the amount of vino/grolsch drunk and the amount of CAd errors occuring! :dizzy: :D
Green Giant:
A really simple thing for a fan to cool off the cpu is a cheap 10" vortex fans. They push more air than any form of computer case fans, along with being quiet. A duct from the outside to the back of the fan would suffice in creating plenty of air flow to the whole cab, hot air rising and all.
If you are pulling in enough air from the bottom, you won't need much of anything at the top unless you are worried about your monitor warming up.
Franco:
Thanks for your post Green Giant. You will see from the models below that space is going to be at a premium so I dont think I will have enough room for ducting. Im pretty sure of what I am going to do cooling wise which I will post at a later date.
I have started to make a CAD model of the type of thing im looking to make. Ignore the colour scheme, im thinking of doing the whole thing in black vinyl (possibly textured) with chrome t-moulding and stainless other parts, I am quite liking the blue/chrome though! Ive diplayed it in blue as it is hard to make out alot of the image with black panels.
These are a couple of views of my design so far:
I have decided to have quite a chunky top on the cab. I quite like the profile as it looks almost space invader'ish. There will be chrome t-moulding around the top but I have not added it to the drawing so far. Also note I havent added the glass as yet (ive modeled it but it seems to mask the raster SF2 image).
This is a close up of the CP areas:
Im going to make some button bezels out of stainless steel to surround the control buttons as well as the buttons on the front of the CPs (Player start and credit). Im also going to make some stainless dustwashers to match.
The eight white dots around each joystick are going to be short cylinders of perspex laid into the CP with a LED mounted from the rear side to light them (thanks for some inspiration on that one theCoder!)
The CP buttons are all going to be clear with LEDs controlled by a LED WIZ and Mala.
Im also going to make some heavy duty stainless steel feet to raise the cab off the floor. Im going to turn some wheels and mount them in on of the legs so that one end of the cab can be lifted slightly to whell the cab around.
Im going to use a 22" flatscreen CRT monitor in the cab. I made a rough model of the monitor and based the cab around it. You can see from the picture below that there isnt going to be much spare space but this was planned as I want to have a large screen to cab size ratio.
The white/grey areas behind each CP are going to be made from some UV reactive perspex that I have and are going to be backlit with UV LEDs.
Please ignore the 1 and 2 on the front of the CPs, im going to have some 1 and 2 player 'man' images instead.
I think that there is plenty more that I have forgotten to post but im quite tired due to the amount of time I have soent on CAD this weekend. Ill update the thread tomorrow when I have remembered anything and when I have updtaed the models.
Any thoughts/suggestions etc so far?
