OK, got my Zino in today (yay fedex saturday delivery of regular shopped items!).
Couple of quick notes on teardown.
7 screws to get everything out, all simple #2 phillips. so no drama there.
i got the $499.00 more power version, and
BOOOOO! no installed IR receiver, so you must have to order it with the dell remote to get it internally installed, unless Java Jack wants to tell us the DP/N on it so we can try to order it separately.
(look here:
http://support.dell.com/support/edoc....htm#wp1186672 and if you wouldn't mind telling us the DP/N it should be able to be ordered as a replacement part, the tag should be wrapped around the cable.

Thank you in advance if you can do this)
standard tray load laptop optical drive, once you remove the top cover and top inner cover, it slides out the front for replacement.
standard 3.5" hard drive, Western Digital Caviar Blue 7200 rpm in my case. Hard mounted to the inner cage which is hard mounted to the case inner walls, so if your drive makes noise, it will radiate. something to consider if replacing with a bigger drive.
an interesting note, the wireless antennae wires are actually routed up to the top of the case so that when everything is installed, only the black plastic top cover is between them and the "world".
fan is multi-speed system controlled 4 wire fan. so you "could" hack that for better control or use software controllers if you like.
there are two standard sata ports on the board, but only 1 four wire power (adapter to the HDD) and one 2 wire power (adapter to the optical drive).
there appears to be enough space to replace the OPT drive with another 2.5" drive pretty easily, even if it was one of the taller 2.5" drives, but power would need to be split off from the 4 wire power for the HDD somehow.
I'll be playing with this and setting it up for Blu ray playback this weekend, and then probably can post specific pictures or test specific items for people.
