Thanks to all, I have edited my answer adding "budget". It's the main reason why I need "customizable" laptop. I have pick up this configuration from HP Store, starting with $1446 ending on $1013.04. Check it please:
EliteBook 755 G4 with:
-- AMD PRO A12-9800B (2.7 GHz, up to 3.6 GHz with Turbo Boost, 2 MB cache, 4 core) + AMD Radeon™ R7 Graphics (W5Q99AV),
-- FreeDOS (- $226.00),
-- 15.6" diagonal FHD (1920x1080) Anti-Glare LED SVA enabled for Webcam slim,
-- 8 GB (2x4GB) DDR4 1866,
-- 500 GB 7200RPM SATA-3,
-- Dual Point spill-resistant Keyboard,
-- Intel 7265 802.11 a/b/g/n/ac 2x2 Non vPro +Bluetooth 4.2,
-- Integrated Fingerprint Reader, (it's not important to me)
-- 3 Cell 51 WHr Long Life,
-- Destination Country Kit Localization,
-- 3/3/0 limited warranty and Elite Services Information Card.
I believe that it could be lower if was posible for costumers put aside some choices like Destination Country Kit Localization and Warranty (This is impossible from my country) and CD-DVD unit. I'm looking for some configuration like this. May be would be nice add a primary-SSD storage device and better battery.
