Lenovo Sensei

Question

Hey everyone, I was chosen as one of the top 4 designs to compete in Lenovo's Mod Contest!  I've been working on this project for a few weeks now, so let's get you up to speed.
(@ moderators, if there is a more appropriate place for this log, please feel free to move it. Thanks!)
Here is my concept/idea:
The Lenovo Sensei is an A700 IdeaCentre with a built-in HD projector underneath, creating an indispensable teaching aid that could replace the age-old dusty chalkboard. Having both components integrated together would enable the teacher to instruct his or her class more dynamically. Assignments could be projected onto a large screen or wall in front of the class. The teacher could run education software, play videos & DVDs, and keep track of all the students' progress, all in one compact unit. Think of it as the chalkboard of the future! Features include:
    * 23" widescreen LCD monitor with Touch Screen capability
    * Slot load blu ray drive
    * Integrated DLP projector 1280 x 800 Resolution
    * Hybrid laser/led technology, 3 low wattage power modes
    * HDMI connection between A700 and projector
    * Well-ventilated housing to keep system cool
    * Cabling kept to a minimum, with only power cords emerging out of unit
    * Buttons on projector relocated as well as other I/O ports to maintain functionality
With everything that the all-in-one Lenovo A700 offers, paired with the detailed display capabilities of the DLP projector, the teaching possibilities are virtually endless!
Here is the A700 set up on my desk.  Came with wireless keyboard, mouse, and an air remote control.
Removing the back panel, you can see the slot load blu ray drive and the computer cover.
Taking the computer cover off reveals the hard drive enclosure and the motherboard.  I was surprised to see a full-size drive and not an SSD.
Here is the DLP projector I'll be integrating.  It's a Casio A240.  I chose it for it's low profile and energy efficient lighting system.  It has 3 power modes: 270W (Eco Off) / 190W(Eco On Level 1) / 130W(Eco On Level 2)
Rough placement of the projector, centering the lens with the A700.
I'll take some measurements from here, and construct a cardboard template of the new base that will house both components.  I've been doing some design mockups in Sketchup, so once I finalize that, I'll post up some preview pics.
Thanks for looking, and good luck to the other modders!

Answer 1

I wanted to add some extra functionality to the case (you can never have too much functionality), so I decided that a built-in removable drive bay would suit this mod nicely.  If this was employed in a multi-user setting, each person could have their own drive to keep their files, rather than on the system itself.
I really like these Seagate Free Agent "Go-Flex" drives.  This one is a 1.5Tb drive, and is USB 3.0 (unfortunately, the A700 doesn't have USB 3.0 yet, but I can still use the backward compatible cable in a 2.0 port).
Comes with the usb 3.0 cable and a detachable rear connector.  The detachable part is standard sata data and power.  This will be built into the pocket the drive will slide into.
Built a pocket for the drive to slide in to.  Drive fits snug inside.  
Removing material to make way for the connector.
Fits ok.  Now to glue the connector in permanently to the pocket.
It's not glued yet, but this is how it will look once finished.
 And once I get the main base put together, I'll cut an opening in the side where this pocket will go, and glue it in place.
