The dark copper coating and the black derlin top sounds like a wondeful match with the DARK mobo.    Having something engraved on the top would be cool,  or having the top thick enough to make it easy to engrave would be a good runner up.

Derlin top...  That's pretty HARD-core

I should be able to give a deposit anytime if that helps (even if I cannot purchase till Oct.)  

Thanks again Nate!

I'm also an Aussie who's in 100% I'll take a Matte Black Copper + Delrin with Black Oxide fittings would be, as you put it, DEAD SEXY... :D
 
Now just to get the board to match it. :D
 
Would it be possible for you to engrave onto the Delrin Top X79 DARK or something like that?

I can do anything, but the idea was to make it simple.  The more time i mess with the block, the more time it takes to make.  There isn't much room on the block, its pretty narrow.

However, if you guys want to come up with a logo for it, lets see whatcha got :)

I have zero photoshop skills, so I can't really make it look pretty, but this was my idea done in MS Paint... So a little imagination is required.... 
 

thats kinda big for the heatsink

Fair enough, was only a thought...
 
But I'll still be in for one.

I am working on vector art ATM but as I have no dimensions in regard to engrave-able area
on the block, you would need to resize it accordingly (and of course add your tooling path).
I will set it up in proportion to the block images you have posted.
Is a vector .eps file ok?

Custom engraving is an additional $150.  

lol ... in that case I will engrave it myself =P
