go with the falcon, they are better than xenon. saying that I have a xenon and it runs perfectly and has done for a couple of months now. I find if you keep it stood up right it will stay cooler. I also run the fans at 100%. The first xenon I had I bought from consolewizards and it lasted a weekend. I made this one and its been running as my main console for over 2months now. the temps are high 75 - 80 but its lasting. the first ones temps were between 50 and 70 and that broke straight away. I think the reason this one is lasting is because I dont use it for modding. the first one red ringed in the middle of a lob. I hope this has helped.

Get a RGH2 slim from ChromeMods, only $125, best deal out of all of the trusted sellers, and it should cost you about the same as the Xenon or Falcon. But if it is between those two get the Falcon, R-JTAG boots instantly 90% of the time and the other 10% is a two glitch. I've never had or seen anyone with a R-JTAG take longer than two glitches to boot
