Re:
I can't help identify the frame exactly, but I'd agree it's a mass produced ally frame (but how many bikes don't fall into that category these days anyway?), instinct tells me that it's nothing to get too excited about.
Maybe a few more pics of the frame would help someone else to identify it?
If you have some scales then finding the frame weight would be interesting.
To say that it's nothing special is not necessarily a bad thing, plenty of people on this site have a lot of fun riding bikes that were pretty bog standard when they were produced, so the only way you'll truly know what it is like is to build it up and ride it.
And hopefully at some point you'll discover what frame it actually is.
