Man, this is so weird. Earlier today, I found this old thread after doing a search for Street Fighter projects and here it is updated and back on the front page. Great info already in this thread. I learned from your thread that I also have Dynamo HS-1 with a 19" monitor just like The Dude and Max here. It looks like a vagrant slept in it and used it as a bathroom and moved on, but the outside looks to be a perfect shape for a SF2 cab.
Just looking at your cab so far, I forgot how much I loved and friggin' prayed for one of these damn SF2 cabs back in the day. I'm now inspired to deck mine out with SF2 artwork. It'll be expensive at around $169 bucks to do it, but I think I'll do it. I'm using PC parts though, yeah I know, I'm a f**kin' amateur.
Anyway, keep at it and post lots of pics!
PS, nice stang!
