I wouldn't expect to get a lot of other stuff funded.
Typically those bikes, - same frame was sold from a number of brands like Ironhorse, Bogner etc., there is a more specific version for Diamond Back -, are not selling fast and expensive, because there is no big fan base any longer, even if with that bike design also DH races have been won.
BTW: the used components and the fork on yours make me wonder if this bike has original equipment?
Never heard or seen a "Forkwar" fork, typically Sintesi had Marzocchi forks.
The entire group seem to be replaced in more recent years, right? To me this tourney and other entry level stuff, in particular the crank with chainrings cutted out of a sheet metal and the brifters are also everything but helpfull to sell this to a classic bike fan.
Just wanted to manage a bit your expectations, you should think of rather keeping this bike for yourself and have once in a while a bit of fun with it, selling it won't bring a lot, maybe 150-250 bucks to give you a first idea.
