Hello toaf and jnjroach,
From what I've seen you're right toaf about the screen - I've found a top rated guy who does grade A screens (full front unit digitizer etc) for £149! And he asks for the serial # - model # just incase and takes returns - so that parts nicely sorted.
Funny thing is the Pro 4 screen costs £149 and a Pro 3 screen costs £249.
Good point about the Pro 3 being a harder nut to crack than the Pro 4 - I really don't what to break a screen just so I can get inside.
jnj - In my original post I was talking about Surface Pro''s in genral - rereading it I can see why it would cause confusion.
But I did mean an i3 in that moment I was thinking about putting a Pro 3's i7 motherboard into a Pro 3 i3.
I could get a nice Pro 3 i3 for £250 and a cosmetically battered i7 for £150-£200. Move the parts about and wahla. Nice Pro 3 i7 for £450 + working i3 spares and a lot for tinkering fun
I'm thinking more about doing the same thing but with Pro 4's. But I had already dismissed the m3 because of the things you pointed out jnj.
Pro 4 i5 with type case and pen for £550 is looking very tempting.
A cosmetically battered Pro 4 i7 16gb regularly selling for £370. That's a lot of cash for something that doesn't work lol
But IF the switching of the guts works out okay - it's a very cheap top spec i7 and every day is Christmas for me
I think I'm going to go for the Pro 4 i5 (4gb) for £550 and if I'm feeling flush or in a tinkering mood ill buy a cosmetically battered i7 and have a play. Bear in mind the Pro 5 is just round the corner so prices will come down a lot especially on spares and repairs parts.
Thank you for your thoughts it's helped clear up the whole compatability worries I was having.
I'll post back and let you know if my little experiment was a success or a dismal failure haha
Thanks again,
Steven
