I'm planning to build a two player bartop cab for as little money as possible, as the only reason I've been able to even start this is that I have bought a house- the dream is someday to have a few original cabs but as I'm desperate to "get my game on" it's time to jump into my first build I think

Anyway like so many others I have an Xarcade (two player without trackball) and was thinking of gutting it, moving the buttons to a location I like on a bit of MDF, drilling and bingo... custom cp completed!
Is this is huge mistake? is there any reason that I should be looking at buying a set of sticks, buttons, and Upac to properly build my own?
Keep in mind I'm trying to keep the cost down, and the xarcade already has everything on it that I need.
Thanks, and you'll all hear much more from me as my build kicks off... very much conceptual stage at the moment (first ever wood work job was last weekend! )
(p.s mods please feel free to move if this is in the wrong part of the forum)
