Hinge/Design Question

This is my first post here at LJs, I have been a long time leech of information and stalker and I can't even begin to tell you how thankful I have been for the information contained here. First of all, thank you to all who contribute.

I am currently designing a new computer cabinet/desk and I have a question about the best way to hinge (which hinges to use on) the doors. I am not planning on putting a face frame on everything, and I have small clearance drawers right behind the doors, so I don't think I will be able to get a regular european hinge in there.

My only thought was to use large decorative strap hinges on the outside, but I really really don't like the look of them and would greatly prefer concealed hinges if it is doable without having to change my drawers around too much.

I'm coming to ask for advise from the pros on what options I might have or if I need change my design.

Hopefully I can correctly add these images to help show what I'm talking about.

Thanks for any and all input.
