All i know in german is i dont speak german. 
Thanks for the link Corgain.. looks like a bunch of reading to do.
The Xbox i have aleady has a network port and 500gb hdd (probably was one of the last non 360s made). Its just been sitting on a shelf forever .. have a Xbox live subscription code someplace as well.. (might be lost)
Ranna you said i could use any regualr dvd drive as a replacement (got loads of those) .. I take it ill have to rewire the power connector as its using some custom connector.. do you have any links on that.
Thanks for all the help looks like some reading is needed...
Hi,
no problem just connect the regular dvd drive with an Y-cable to the internal power connector of the xbox hdd.
The y-cables you usually use for PC's.
It has to be jumpered to slave mode if I remember correct and
you have to use the open button of the dvd drive.
This setup is good enough to flash the BIOS and prepair the box for network use,
mostly you have to do this anyway because of the fact that the original dvd drives
have a big issue with reading burned cds or dvds.
The original dvd drive has an extra connector the little yellow or brown cable that is used to provide power
and connect the open close button. You can disconnect this while you have the other dvd running.
the only problem would be to play original games,
but with a modded box you simply can copy the games to the hdd and play them from the hdd direct.
There was also a way to replace the original drive with a samsung 616 regular pc drive, you have to
replace the firmware and you can connect the original power and open button cable and so it would work
as a full internal replacement with all functions but I have no idea if this drive is still available.
I recommand the tutorials on
www.xbox-scene.com and if you look for a nice and cheap mod chip
look for the duo x2 it costs about 10$ and does the job
