Sounds like way more trouble than it's worth.
It is, which is why I paid for one that someone already reballed with a proper leaded solder mix.
The console does not run super hot with a good TIM so under normal operations it will not get hot enough to damage the board again.
The one I got was a full refurbishment so all sorts of stuff was done to restore it to better than factory condition.
The video against reballing does not apply to the PS3 since the chips and board are good quality but was hindered by the bad solder mix caused from the rapid jump from lead to lead free without companies getting the formula right. The lead free mix now is a lot better and devices that use it show since the failure rate is not like the early days of lead free.
I guess the only thing that makes it troublesome is the hit to the pocketbook.

unless you know someone who specifically has experience with this, it is a huge pain in the ass. According to the videos above, it also seems questionable as to how effective this is. I'd say just get a slim and be done with it lol.
The video starts fine with stuff about poor quality chips which reballing will not fix since it is the chip, not the physical joints that are bad. Then the guy throws in conspiracy theories about internal hardware timers that cause the board to commit suicide after warranty runs out.
This is not true and failure rates are based around quality of components which can be lowered to lower the life expectancy of devices but come on a suicide timer, seriously?
The PS3 in this case was made with the highest quality components within reason since it is a launch console and thus are produced before any cost and power savings measures are implemented. There are a few PS3s out there where the actual GPU or CPU chip was defective and thus recall would do nothing but that is to be expected but most failed from the solder joints themselves being brittle from an early mix of leadfree solder that was rushed into service with little testing done. This is why reballing works for game consoles like the PS3, as the problem being fixed (the solder joints) is the problem in the first place.
