Just curious, are u going to use soft15k with this?

i'm not even sure what that is. I've heard of people talking about it...i was under the impression it was for getting your video card to output a specific singnal to get it to work with an arcade monitor. Is there some benefit to using this with a PC monitor?

I thought i've read somewhere that it will help getting a better picture on a LCD (when i say better i mean a more stable, feks. on my lcd monitor today when playing 1942 it often gets a large "scanline" across the monitor kinda like a lag, hmm not easy to explain it), not sure if that included a PC monitor. Problem is that i dont remember where or when i read it, maby i just imagine i read/heard it somewhere... :-\ the only way to find out is to try it (i can do that) but first i need a harddisk so i can continue on my project (install xp, mame, configure joysticks etc)
U ask why i dont already tried it on my stationary PC? well its running win7 and having a nvidia 280 gfx, and there were warnings when i launched soft15k wich said " Please note that Geforce 8 series, geforce 9 series and geforce gtx series cards most likely dont work without the EDID dongle. " dont know what a EDID dongle is, and a second warning " Please note that vista support is considered experimental an has several limitations". So i think i wait to try it until i have my pc up and running with XP.

that scan lag is probably screen tearing...try enabling the tripple buffer option in your mame.ini (or if it is just a certain game, in that game's .ini file.) i had that problem when playing Rastan, enabling triple buffer fixed it.

OMG so simple solution thanks SeverdHed

well, i didn't have alot of time to mess around tonight, but i did get an hour or so. i got the motherboard mounted inside the cabinet. i mounted it to a separate board so it can be removed easily.
i took a few more pics of the motherboard mounting, as well as how i secured the video card, but i took them with my cell phone and i dont have the cable downstairs here with me at the moment, i'll try to dump them tomorrow.
i also started playing around with the monitor, since it is by far the biggest challenge of this project. i thought about removing the case, but upon opening it up, i wasnt sure how i would secure everything...so i put it back together. i ended up just sitting it in the cabinet on some boards that were already mounted in there from the factory. the front board was clearly used for the original monitor, but i don think the one in the back was. i had to play around a little bit to get it into position where it didnt stick out the back of the cabinet. i had to put a small wooden block at the back to get the door to go on. i screwed two small boards together, and attached them to the monitor shell from the inside, using small screws.
it is too late tonight to use the drill because i might wake the kids, so it is just sitting in there now.
i masked off the screen and spray painted the bezel black so it would be easier to hide. since the inside of the cabinet is all black, and there was a paper bezel in there that needs a little adjustment...but behind the tinted plexi, it just looks really dark..so i dont think i have to be too particular with how that turns out.
i still need to secure it in there somehow, but it sits there pretty well for now. i dont have a power supply for the PC I am using, so just to give it a try, i hooked up my laptop to the monitor and fired up mame...
tomorrow i hope to get the monitor secured, and start wiring up the controls.

Here are a few pics of how i mounted the PC components.
i used someone's suggestion on cutting up a bic pen (i dont remember who suggested it, but it worked great) i just took apart a pen and cut it into relatively equal sized pieces with a razor knife.
i marked the screw locations on the board by placing the motherboard on it and marking them with a pencil..then i predrilled the holes. then i placed the pen pieces over the holes, and proceded to screw the motherboard down using ordinary wood screws.
the motherboard i am using did not have on board video, so i had to use an AGP video card. i had to find a way to secure it so it wouldn't get knocked loose if i moved the cabinet. so what i did was bend the bottom of the metal back plate up at a 90 degree angle, and drilled a hole in it. then i cut a longer piece of the pen and then screwed it down to the board just like i did with the motherboard. this keeps the card held tightly in place.
here is just another shot of the mounted board:
and here is how i mounted the hard drive. i had some brackets that were designed to attach to a hard drive on either side, so it could be mounted in a 5.25" drive bay. i just used one of them, attached it to the hard drive, and then screwed it to the board with wood screws. i placed a piece of craft foam between the bracket and the wood to help dampen vibrations.
on a side note, i thought i was going to have crappy pictures, but apparently my cell phone takes better pics than i thought.
