Your reviewer appears to have photographed two different motherboards.
The images on pages one
http://images.tweaktown.com/imagebank/p35t_1intro.jpg and four
http://www.tweaktown.com/popImg.php?img=p35tl_6.JPG show three main areas of difference:
1 - The DDR3 slots are reversed in orientation. P1 shows the positioning notch closer to the CPU end of the board, while P4 shows the notch closer to the PCIe slots. The silkscreened model information near the DDR3 slots is also slightly different, lacking the CE certification on P1.
2 - The heatpipe system is different. P1 shows two heatpipes from the northbridge array, lacking the huge tower of fins, to the rear MOSFET sink. P4 shows a single pipe, and includes the grossly overdone array that has put me off the DS4/DQ6 models already.
3 - Several of the electrolytic caps have the coloured tab changed, probably indicating differences in capacitance.
These variances, especially #1, lead me to conclude that the picture on P1 is of an earlier demonstration model or prototype. This is unfortunate, since I prefer the cooling arrangement of that model to the ergonomic nightmare of the final DQ6 El Grande.
