I never even noticed it was a BD drive! Was just a spare I had lying around the place.
A few things for people debating/currently building one! Most of these things are hard to find out I found (alot in wiki to be fair)
Power:I used an 'intelliplug' (UK/Ireland version of the power lead that switches everything on when PC is on) Allows me to press one button and turn whole cab on or off!
http://www.oneclickpower.com/store/ Its a must have in my opinion!
I used a PC power supply to power most of the DC stuff like LED's, Neons etc! To get it to come on you need to short pin 14 with 15 or 16! Its the green with any of the 3 blacks beside it!
TV:To get the TV to come on by itself without a remote control, just wedge something into the power switch to keep it pressed! This will make it auto come on (on most TV's)!
To get the TV to automatically go to AV, put 12v to pin 8 of the scart (and ground to the surrounding metal bit)! I used a 12v power cable, but it would probably be easier to take the 12v from somewhere inside the tv!
Artwork:To get my image on my CP (its called cosmic frostbite) to be clearer, I used 'gaussian blur' to blend out some of the pixelation look.
Mamemarquees wanted something like $130 for my CP and marquee, I got it printed in a local sign shop for 30 quid and that included putting the marquee on acrylic!
General points:As a rule of thumb I found when designing the size put the top of your screen at eye level minus 4 or 5 inches! I looked into this alot and found this is a good way to go about it! Of course it all depends on your preference or angles etc but worked for me.
For the rom side of things "romcenter" is great to name your roms right and delete all the junk! Then "fuzzy renamer" is brilliant to get image/video snaps to match names with the rom itself! This saved me so much time in messing with roms!
Got to recommend emumovies to get the image snaps/videos from! Has everything you would want!
Other than that this forum has absolutely everything you could possibly want to know about it and if not someone always knows on here so thanks to all!
