Yeah its a gamble as always with these things. Luckily never had to declare, just walked straight through as there's normally isn't anyone there to check.I think their 5% sales tax prob helps. if you bought that to the UK (and declared it) you'd have to add 20% VAT.
Overboard is an understatement, it's so unnecessarily big though how much heatsink actually matters i don't know.Look at the size of the gigabyte aorus and Asus strix, for example. They really went overboard to say the least.
