Here is a review of the cooler you've listed:
Ultra ChillTec Thermo Electric Cpu Cooler
Note the most recent review is 2007, which then raises the question: Are there any technology revisions between then and now. A quick search on google shows the cooler costs about $90.00 retail. Looks like Cyberpower is charging that and then some. Admittingly, I don't know anything more about soild state cooler that the review article tells you.
But none of what I have written above answers your question. I do believe the cooler will handle overclocking at the levels provided by Cyberpower (so taking a 2.66GHz to 2.92GHz or 3.19GHz if you choose the 10% or 20%, respectfully.) I make this assertion based on the fact that if the CPU fans they install don't do the job then they have to fix your system at their expense (less shipping). Companies don't generally install parts that won't work intentionally.
If you plan on tweaking the system after you receive it then I'd recommend taking a look at www.frostytech.com .
