How to say "casing" in Japanese

• 筐体きょうたいCommon
  nounThe case or housing of a machine, computer, or similar device — the enclosure around the working parts; also the cabinet of an arcade game. The common word for this sense.
• ケーシング
  nounThe katakana loanword for 'casing', found chiefly in technical and industrial contexts. Less common than 筐体, and for the body of a computer or appliance 筐体 is the word you want.
• 外箱そとばこ
  nounThe outer box or slipcase: the packaging around a product, as opposed to the casing of the machine itself. For a device's case or housing, 筐体 is the word.
• 外被がいひ
  nounA protective outer coat or jacket around something — closer to 'covering' or 'housing' in a protective sense. Seldom the word you want for the everyday 'casing' of a device; that is 筐体.

For the case or housing of a machine or computer use 筐体; 「ケーシング」 is the loanword in technical use; 外箱 is the outer box or slipcase; 外被 is a protective outer coat or jacket.
