I have a few items left over from various arcade projects and I'd like to see if I can trade up enough to purchase a spinner from GGG. 
I have a mostly disassembled laptop. I soldered wires to the power button and I removed the LCD screen. It works - you need to hook up a monitor, keyboard and mouse. I was going to use it in my last project, but decided to use a full computer. It's a Pentium III 500mhz, 128mb of ram, 10gb hard drive. Good for a classics bartop or cocktail. Sluggish(unplayable) when playing Smash TV, it had no problems with the classics. 
Dell Dimension 2100. Pentium 3 with 256mb memory, 20gig hard drive. I believe it's a 800mhz machine. The onboard video is not suitable for mame - you will want to use a PCI Video card instead (there is no AGP port). 
2 brand new x-arcade joysticks still in the package, and 2 used x-arcades and a few x-arcade black buttons. 
Over/Under Coin Door in decent shape. I have no idea if the coin mechs work. It came out of a working dart board. 
2 80mm neon blue case fans. 
20ft 3/4" light blue t-mold. 
3 10" CRT monitors. 
1 19" CRT Flatscreen monitor from Mitsubishi. (this is not a LCD). 
PM offers to me - I'll let the stuff go for any reasonable offer. I'm in St. Louis if you want to do a pickup.
