Bottom cover off the Dell Pro Precision 5 16s Intel. One blower fan at the top left, the mainboard across the top third, and the 70Wh battery filling the lower half. The two speaker modules sit in the bottom corners, away from the keyboard deck. That battery is what returned 24 hours and 43 minutes on our PCMark 10 office battery run, the longest of any Pro Precision we have tested. Dell keeps this one serviceable too: the memory is LPCAMM2 rather than soldered, and the SSD, WLAN card, fan, and battery are all replaceable.
