My tower kit arrived today, I can see where the 'DIY' comes int it now at least!!
Anyway I have the FrankenMiga running complete with Eyetech's keyboard adapter, my Mediator 1200 LT and a Voodoo3 2000 pumping out 800x600 @ 32-bit. I still gotta build the tower but, suffice to say, I am at last happy

I'd like to thank Alan Redhouse (again) for paying attention, being honest, and answering everyone's queries in this thread. I'd also once again like to thank 'Ryu' for getting various wheels into motion and bringing the situation to Alan's attention.
Anyone who has not recieved their goods yet - have patience. Mike - relax they are doing a lot with very little at Eyetech, give them a chance. Also if you plan on modifying a case from Maplin that is the same price I'd say don't bother, get a DITY kit from Eyetech, it's the sam price, does the same thing and is also guaranteed to fit the A1200!
