Excellent!
LDLC service is flawless, as usual.
Very, very powerful PC, does not heat up in normal use, no noise in office use (from 0 to 22db). 40db in intensive calculation.
Very comfortable screen, excellent SSD, limited connectivity (few USB, no card readers, etc...).
Slightly adapted (even bizarre) key layout, which may disconcert professionals a bit. (no right-click on the keyboard without a function key), well placed numeric keypad.
Lots of crapware for the backlit keyboard, system monitoring, power profiles (4 additional to Windows; "Quiet, Performance, Turbo, Manual (for GPU overclocking)".
Excellent machine, untested in games (but I'm sure it does the job), replaces a desktop for intensive computing.
A very good investment.
