Interesting, that. It is heavier than water, so I imagine it will leak faster... As for it reacting to seals etc., isn't it supposed to be totally inert?
Anyway, we have been discussing this issue a bit on Wizdforums.co.uk, and one poster could share his home PC experience on Fluorinert:

perflurocarbon liquid cooling works well !
I just came across this thread, with read with interest some of the comments regarding perflurocarbon based liquid cooling. As I've been using this stuff for almost four years, I thought I could add some useful informed comments.
Just to give you an idea of cooling performance...
I'm writing this post on a liquid cooled PC-DL with dual overclocked 1MB cache Xeons (@3.6GHz), a 9800XT and northbridge all running with liquid blocks. The system is cooled by a Koolance EXOS and it's using InertX PF5080 perflurocarbon coolant.(www.InertX.com)
The machine currently holds the no.2 fastest PCMark2004 score on the futuremark orb site.
The Koolance EXOS never needs to be out of mode 1 (low noise mode) and the temp. now (i.e. under light load), is reading 35 deg.C. The point is perflurocarbon coolant works very well in place of water, even on a consummer friendly small bore pipe (6mm) liquid cooled system. If I fire up Seti@home on one cpu and run FarCry at the same time on the other, the Koolance will hit 42 deg.C tops. MBM is registering the CPU's temperature from the mobo about 4-6 degrees hotter than the EXOS disply. The EXOS temp probe is stuck to one edge of the underside of CPU 0's liquid block, and is designed to give you an idea of the coolant temperature. Using a Calex digital temperature prope to measure the real coolant temp. in the EXOS reservior, and hey presto it also reads 35 deg.C.
(MBM currently shows CPU0 @ 41deg.C & CPU1 @ 39deg.C)
Not bad when you consider the thermal load.!
There seems to be a lot incorrect information flying around on the web regarding the cooling performance of perflurocarbon coolants. Of course it's mainly by spread by people who have never actually used the stuff. I'm only trying to set the record straight here, as the advantages of using this coolant are numerious.
Re: it's use in Cray supercomputers.
Most Cray supercomputers actually use conduction-to-convection cooling.
A large aluminium coldplate in is direct contact with heat producing semiconductors (just like a PC water block) with Fluorinert FC-74 flowing through it. In recent times only the T90 series from around the mid to late 1990's used direct immersion cooling with FC-77 coolant, and Cray only built a handfull of those. Today there are very few T90's still in service, and the remaining T3E's and I believe the new X1 all use coldplate/Fluorinert cooling.
I'f anyone is interested in using this stuff for PC liquid cooling, I'll be happy to share what i know.
and for the Myth spreaders out there...
It's not toxic, unless you burn it. (usually above 200 deg.C)
and it doesn't destroy the ozone layer.

I also know that on some Crays the PCBs are actually submerged in circulating Fluorinert, and those carzy monkeys at OCTools.com have submerged entire mobos in chilled fluorinert baths. So I must admit I'm a bit confused about this whole static electricity thing, especially as Fluorinert doesn't conduct. In any case Amari inc. seems to be happy enough to use it in PC systems that they sell. But if you can give me a link to said documentation, I would be grateful and will read it immediately.
