Xecuter 3 modchip for Xbox? Any idea what this does?

[Melo255]

So...without knowing where to post this I figure there are enough smart and easy to follow people here that can explain what this is to me. I'm trying to find out what an Xecutor 3 modchip with a 120 GB hard drive Xbox does exactly.

Does it allow the user to burn/download games onto the hard drive somehow? The xbox in question comes with 33 games already (I imagine they are loaded onto the hard drive but is that assumption probably correct?) I'm asking because I think I can get a very good deal on just such an xbox (NOT a 360) but I want to find out exactly what I would be buying.

ANY help would be very very appreciated as I am essentially a complete moron when it comes to things such as this. Thank you,

Michael
