I am looking for a reliable XBox 360. I bought a white one on eBay and about 3 months later found out that it had been moded with spacers/ washers. I went ahead and re-seated the heatsink with the recommended silver solder and it still got the Red Ring of Death a few weeks later. I have everything but the actual console and I just need a reliable one. Should I look for an elite? Is there a way to tell which of the consoles have the bad solder in the boards? Is there something I do to prevent overheating besides providing ventilation?
