Unless you're in love with this frame, I'd sell the eno and buy a complete bike. The redline 925 has everything you want, though you'll have to find an '07 to get mustache bars. The raleigh one way is also great. Both are under $600.

Are you sure the Panic has enough tire clearance? I googled the tires you're talking about and they only seem to come in 37, there aren't too many frames that have vertical dropouts and clearance for a 37 and a fender.
