600g cooler should be fine, just move your case carefully. If you want a lighter alternative consider a Zalman 9500, its around 525g, i own this cooler its not the baddest but does the job and i move my case to clean it and its fine. Also, there is the Thermalright Ultima-90 at 460g, but you have to buy a 120mm/92mm fan for it which adds around 100-120g more to the weight, but this thing is a great performer coming close to it's bigger brother the Ultra 120 in terms of coolling.
Congrats on the case, BTW. I have the similar TJ-09BW and its awesome, though wire management is it's only drawback.
Edit: didn't see that you are going to take this on a planee with you 10 times a year. Get a a much smaller case like Thermaltake lanbox or a small mi-tower. TJ-10 is too big for that.
Edit 2: the 7200.11 gets beat by Samsung F1 and WD Se16, Velociraptor is on the way as well, if you gonna stick to your high end build specs get one of those & run em in raid 0
