I am aiming at £170 for a basic A4000 version (USB, IDE, SDRam and 220Mhz Coldfire) however it depends on lots of things so it could go much higher, specially as a lot of people want Ethernet (10/100) as that isnt cheap.
So how much more would it cost to do a whole motherboard? :-D
By the way, I was thinking about putting a pegasos into a cdtv case, any thoughts here?
