Xbox 360 Mod HTPC

Hi guys,

I've sparked a new project in my head and I'm very excited about it.  I have an xbox 360 laying around that i havent turned on in over 3 years.  My current HTPC is a 7 year old surplus Lenovo M57.  I think it's time for an upgrade.  And what's a better way to re purpose a sad old 360 than to gut it and drop in a mini itx board!??  

So I need some help.  I've never done any modding this extensive before.  for god sakes, I don't even have Torx drivers so this thing is only half disassembled haha.  

Does anyone have ideas?  Things I've thought of that require some planning would be Power... how would i power this thing?  could i use some sort of external brick?  or possible even use the existing xbox power supply?  Might need to get creative to mount both an SSD and 3.5 mechanical drive in there.  I think I can do it, but i need suggestions 

To mount the ssd or hdd, you should be able to easily modify a existing xbox hdd to hold both of them very easily if not 1 is a sure thing since the xbox hdd is a 3.52 drive stuck in a stupid case and running the sata cable and power cable to them should be easy enough.

Hopefully that gives you a bit more room inside the actual case. 

I've never had an Xbox 360, so I'm just going to assume that no GPU will fit.

Probably an AMD a10-6800k or kaveri when it comes out.

M-ITX board + PicoPSU + external power brick

ddr3-2400 2x4gb or 2x8gb, or of similar clock speed, with low profile heatsinks.

Noctua NH-L9i low profile cooler.  Or stock, if you don't have the budget.

Maybe an M-Sata if your motherboard has the slot.  Then use the 2.5" laptop drive from the XBOX for mass storage.

Youll need a dremel.

You could see if you can fit a discrete GPU with a 90 degree PCI-e daughterboard. They aren't particluarly easy to find, and most are only pinned for PCI-e 2.0, but it would work to allow for much more room. I know the Alienware X51 uses such a method.
