I am designing my own case in aluminum with heatsinks on the sides and heatpipes to transport the heat to these two heatsinks, see the image to get a preview. The sides have not gone through any engineering process in calculating heat dissipation or anything, I bought 10mm thick aluminum plates and asked a local cnc-guy to prepare them according to my drawings. The sides are designed for pleasing the eye at the moment. If need be I will order real heatsinks and carve them out for appropriate shape. The plan is to cool the CPU on the right Heatsink and the GPU on the left heatsink. I have all the heatpipes necessary, called Borg HPC and Borg HGC by mcubed.



The hardware I have is an 80Gb Samsung 2.5 HD (Suspended), the Silverstone passive PSU and a slot-load Pioneer drive DVR-K04L.
I have practically decided to go for a Pentium M or a Core Duo depending on motherboard release dates for the Core Duo. (Tested a 3200 E4 Venice, on the setup with one heatsink which got tooo hot, a Northwood 2.6 533 was better, 34c Idle but got up to 75c on load)
The solution I have in mind right now is a i915Gmm-HFS with a Pentium M with DDR2 or DDR memory. My questions are:
- With reference to the figures for the Northwood, will I be able to cool a Pentium M or Core Duo at all?
- If I go for a Pentium M, does the 400/533Mhz make a big difference? The 400 seems to be less power demanding.
- My target is to be able to playback 1080p WMV-HD and 720p h.264 (Haali+FFdshow). Will Pentium M 745 1.8GHz 400MHz or Pentium M 750J 1.8GHz 533MHz do the job or will I have to get a 2.0Ghz? How high do you think I will have to go for playing 1080p h.264?

- What memory to choose for the setup.
- Any Geforce 6600Gt with low power consumption to cool with the heatsink on the opposite side of the CPU heatsink?
Thanks!
