Heatsinks and Thermal Epoxy - ideas?

[zeropointbug]

I found a couple more heatsinks laying around last night. Just thought I would post them.

The two angle ones are from a PC power supply, and the other one is from an old CPU (Pentium III ?). The one that the case is sitting on... it's like it was MADE for the Quark, it fits perfect.

I just going to play around with these and see what kind of performance I can get from these, before I make the custom Quark case.
