I would suggest you do the following:
Take Logic Board from 15" iMac and install in 17" one with broken LB. You should then have a nice working machine and a decent upgrade of screen for your trouble.
Then take the remains of the 15" and get a standard laptop panel, if it were me I'd probably go for a 1400 x 1050 15" but you could also go a 1024 x 768 (same as standard - pretty low res) or 1280 x 1024 or even 1600 x 1200. Then you'll need a controller to convert the lvds signal to vga/dvi. The iLamp does not use standard lvds, you will need a display with a single channel lvds connector. Most only do up to 1280 x 1024 but I have seen some that do 1600 x 1200. After that figure out how to stuff the MacMini into the casing (I'm pretty sure I've seen it done - check macmod.com). There are also some folks out there whom have figured out how to get 1 x 3.5" SATA + 2 x PATA drives working off a Mini.
All these things are easily do-able with a bit of waiting (for the right opportunity) and a bit of planning ahead. Another simpler option is to get a hold of a standard 15" LCD monitor and gut it and use all the components from that in the iMac (should be easy enough) which will be cheap (15"ers aren't worth that much) and has all the controllers, power etc... for the display. But I'd go the lvds route for the higher resolution - remember a MM can only drive one display, best to make it a good one.
Personally I think you are wasting your time trying to use the existing display - you're in for a world of pain.
Good luck.
