Thanks guys! I like it myself very much too.
The project began when I got my hands on a RRoDded box, which when fixed turned out to be JTAGgable.
I did the JTAG and started to think different ways to keep this precious running as long as possible.
Original case with more cooling wasn't sufficient, so bigger case was necessary.
By chance I found the TT LanBox case being sold in a Finnish pc-forum, liked the looks and checked the specs from Thermaltake website. When the case dimensions turned out to be suitable for XBOX mobo, I made a deal with the seller.
So, now that the case problem was solved, next thing in line was to solve the actual cooling.
Since there isn't really any custom cooling systems (apart from watercooling sets) available for the XBOX, it was time to think something different.
After a lot of measuring and surfing the cooler manufacturer sites I decided to use the Arctic Cooling Freezer 7 Pro V2's.
I had few V1 XBOX CPU coolers lying around which were used as a base for the AC Freezers to mount. I stripped the V1's metal heatsinks & pipes from the base, sanded them down and took the bases and Freezers to a local radiator repairer who welded them together (easy job for a pro!).

With one dead Xenon mobo I started to fit it into the Lanbox. Some metalwork was needed, so I didn't want to expose the JTAG to any metal dust, dropped tools etc.
Mobo sits on original xbox bottom plate, which has been "extended" from the backplate (where the twin Coolink 120mm fans are) to the top of Lanbox case. Plus I can use all the original connectors at the rear without any unnecessary custom work.
The bottom plate acts as a mobo tray, which can be drawn out from the behind of the case if needed.
After fitting was done and fans assembled to the backplate, it was time to make few wire extensions; the SATA cable + power for the HDD, extension for ROL connection and for the USB ports.
At this point I discarded the intention to use the optical drive - mainly because I wanted something "fancy" for the frontplate of the LanBox and got my eyes set at the NZXT fan controller which is dual 5.25" sized, so it didn't leave any space for DVD drive anyway.
The ROL needed a little custom work and is actually turned 90 degrees clockwise for easy fitting.
Little tuning here and there, few more fans and temperature sensor placing etc. and the box was ready.
Fan controller temps (and we're talking about Celsius' here) aren't ofcourse the same as in FSD but you can get the roundabouts from them while ingame.
