Firstly, apologies if this is in the wrong forum.
I have Five Xbox.
I set up and Xbox which boots directly into Coinops, but the ungrateful bastards

I wish to make one onto a dedicated media server (running XBMC), which will be connected to the TV using a component cable (Ialready have one), and networked so that I can transfer media files to it to watch.
My question is which version of the Xbox is the best for running XBMC?
Since the machine will be near the TV I want it to be quiet, and have a 500GB hard drive or larger.
Mine are:
# _Version _ TSOP _HD(GB) _Curent use _Comment
1 _1.0 _Yes _40 _Spare _Bad DVD
2 _1.3 _Yes _40 _Spare _Xecutor (2 I think) Chipped
3 _1.6 _No _? _Spare _Standard (Completely unmolested)
4 _? _Yes _? _XBMC _Bad DVD (Old version of XBMC required updating)
5 _1.0 _Yes _80 _Coinops 5 _Bad DVD
As you can see, I have done some work already and have various disks and tools, I have been flashing by swapping a good DVD drive into machins with bad drives.
I have looked on the interweb to try to establish which Xbox is most suitable, but I haven't found a consensus, or definitive answer.
Is one of mine suitable, or do I need to get a Trusty?
Thanks in advance.
