Here's what I intend to do:
Code:

NUT                       NUT
 /    _________________    /
 \    |waterblock/hsf |    \  <- SPRINGS
 /    |               |    /
_\____|__|_________|__|____\_
|H       H    0    H       H|
|H__|____A____|____A____|__H|  <- ALUMINUM PLATE/HOLD DOWN
 H  H[PELTIER]H[PELTIER]H  H
 H|-H---------H---------H-|H
 H|_A_________A_________A_|H  <- COLDPLATE
NUT   [=====CPU=======]   NUT
============================= <- MOTHERBOARD
[---------------------------] <- CLOSED CELL FOAM/NEOPRENE
[---------------------------] <- ALUMINUM PLATE
[_]                       [_] <- BOLT HEADS
(Part of that ASCII is stolen from sunBLADE, since it was so nice. I hope you don't mind, do you sunBLADE?)

A = countersunk hole
| = edge of plate, or tapped hole in plate
H = exposed bolt, or untapped hole in plate
0 = 'socket lug'

I want to make an AL plate, with holes through it, so I can hold a waterblock to it with four bolts. It will also have two pins hanging out for attaching a normal HSF; lugs will be steel, and unbreakable for all intents and purposes. Cold plate and Peltiers are optional, but are attached to the AL plate in basically the same way that the plate is attached to a waterblock. The whole mess is attached to the board via 4 bolts and springs, which are fed through another (1-3mm) plate on the back of the mobo. This will take all torsion off of the mobo, and simply subject it to the normal compression.

PROs (in my mind):
  • The back plate, neoprene, posts can be left on the board at all times
  • Main plate, peltiers, coldplate, and HSF/waterblock are effectively one piece, easing installation and insulation
  • Allows for 'lug-breaker' attachment mechanisms with safety
  • Allows great pressure to be exerted on
    Peltiers
  • Allows great pressure to be exerted on chip, if you want
  • Lots of metal to spread heat
  • Thickness allows you to put in a heatspreader insert, if you have a foundry
  • Works with HSF/waterblock, w/wo peltier
CONs/Caveats:
  • Plate needs to be thick to allow 'lugs' to be mounted--must have same thickness as CPU + socket, more or less
  • More complex than some other designs

I like it though, and as soon as I get a free day that's less than 85F in the shop, I'll make the thing.

Update: accidentally forgot one bolt
