Design Help -- inset drawers


Hey All,
I am working up a design for a two drawer file cabinet -- I am looking to make the carcass out of walnut for the sides and maple for the top. The plan is to make the joints stand out -- I plan on using dovetails along the top two edges. The lower horizontal panel will be maple as well and will be attached to the walnut sides with a sliding dovetail
I am having problems with the design of the drawers and I am looking for thoughts or perhaps product references (in this case slides) that would help. I'd like to make the drawers from walnut faces with maple sides and use through dovetails (this would leave the maple pins showing) If I were making a traditional chest I would use hardwood slides in the case sides and a corresponding dado in the drawer. But in this case I'd like to get full extension on the drawer and since the drawers will be heavy I think I need something mechanical.
I really like the blum undermounts but they seem to leave a 3/16" gap on the sides -- which seems a little big and I am not sure how to make the drawer front cover the under part of the drawer that would be covered if using a standard overlapping drawer front.
My other options is to use a 3/4" wide drawer slide and route some 100# slides into the drawer sides but I am not sure if the remaining 1/4" is deep enough to get a good screw hold etc
Anyway -- thought I would through this out to the masses to see if there were any other ideas floating about
Cheers

full extension hardwood slides are not that big a deal. keyway or dovetail slots in the carcase and drawer side and a floating runner.

One way...
1. Make the back of the drawer higher than the opening by 1/4" or so..
2. Use wooden slides on the carcase, female routed into drawer sides.
3. Shape the slide and dado - dado at top back, slide at front bottom - sort of like a rule joint so that the face frame will stop the drawer back but the drawer can be removed by lifting the front up.
I've made lots of drawers this way, never had one that didn't work fine.

Use undermount slides.
