Just a little tip exploit, if you have been running it on its side. Dont!
The major cause of RRoD in even elite units is due to piss poor thermal paste on the cpu/gpu and heatsinks
It seems to leak out once the system heats up and is on its side. But generally the stock setup is flawed regardless of console orientation, having it on its side is just a no go for it as it almost garuntees the problem to occur.
There is a kit you can buy that allows you to re paste the cpu/gpu and their heatsinks with higher quality stuff and also some thermal pads for some of the other chips on the board that virtually eliminate any overheating caused by Microsoft's bad design. That is if you are up to the opening of console etc, but I know a few people who have done this and had no problems in fact the RRoD issue can be resolved after the fact too if you know how rather than relying on MS support.
