Wow, thanks for the comments guys

The dimensions are : 50cm wide, 45cm deep and 58cm high
Here are the PC specs etc if anyone is interested:
Motherboard: ASRock N68C-S UCC
CPU: AMD Athlon II X2 250 3.0GHz
Ram: 2gb
GFX: Asus NVIDIA GeForce GT520 1GB
PSU: 420w
19" iiyama monitor
2x Ultimarc U360's with Happ Competition buttons
White cold cathode for Marquee
Orange strip and Purple strip LEDs for underneath lighting (I added an on/off/on switch so I can change the colour when I choose).
20w USB powered speakers for sound
The themes were from another site, all I did was change the colours to match my art. All the artwork was created by me and I have a friend who owns a print shop which is lucky LOL I sprayed the cab Cream and the aluminium pieces black around the monitor and Marquee. Since the pics I have added another piece of gold trim at the top of the CP just to finish off the lines.
I may still add 2 more buttons next to the player start buttons for coin, at the moment I use the shift function which works well. The Pinball buttons on the side are linked to buttons 1 & 2 but because they are out of the way it doesn't interfere with other games.
