I actually ordered one of these in blue yesterday. I went for option 2 including the EK GPU block.
If some people actually took the time and bothered to read, they would realize that $799 includes all the watercooling gear, as well as the case/mods.
I actually worked out before ordering, that it's actually more expensive to buy all the parts in the UK and build one myself.
Even after shipping and VAT (if charged), it's works out roughly the same, if not still slightly cheaper.
Plus it comes pre-assembled.
Costs (like-for-like parts):
Watercooling parts (from various UK suppliers) = £571.19
Case (including side window, laser cut front & top rad grill etc.) £229.90
= £800.19 (plus roughly £70 to ship case from US) £870.19
Everything purchased directly from the supplier in the US = $1016.90 (£636.60)
Plus roughly £70 shipping from US = £706.60
No-Brainer IMHO.
