9. The electronic device of claim 7 , wherein the internal platform includes conductive elements that are configured to electrically couple electrical components positioned within the enclosure.
10. An electronic device comprising:
a display viewable along a front surface of the electronic device; and
an enclosure housing the display and comprising:
an outer periphery member defining a first portion of an external side surface of the enclosure;
a front cover removably coupled to the outer periphery member and having a front glass sheet, the front cover defining the front surface of the electronic device and a second portion of the external side surface of the enclosure; and
a rear cover attached to the outer periphery member and having a rear glass sheet, the rear cover defining a rear surface of the electronic device and a third portion of the external side surface of the enclosure, wherein:
the first, second, and third portions of the external side surface cooperate to form an external sidewall that extends along at least three sides of the electronic device.
11. The electronic device of claim 10 , wherein:
the front cover includes an attachment feature; and
the attachment feature attaches the front cover to the outer periphery member along an inner surface of the outer periphery member.
12. The electronic device of claim 10 , wherein:
the front cover includes one or more tabs; and
the front cover is attached to the outer periphery member by one or more threaded fasteners that engage with the one or more tabs.
13. The electronic device of claim 10 , wherein:
the first portion, the second portion, and the third portion of the external side surface cooperate to define a smooth continuous portion of an exterior surface of the electronic device.
14. The electronic device of claim 10 , wherein:
the front cover includes a front metal member that is attached to the front glass sheet; and
the rear cover includes a rear metal member that is attached to the rear glass sheet.
15. The electronic device of claim 10 , wherein:
an internal platform is attached to the outer periphery member and positioned between the front cover and the rear cover; and
