Apple is well-known for high quality PC and laptop cases, although most major companies have fair to medium quality PC cases. Beware of computers with cheap looking plastic cases. If a computer manufacturer uses a cheap case, it's very likely they are also using other cheap components inside as well. Cheap components equal a slow computer which will break after moderate use. If you intend to use a computer for several hours every day, it makes sense to buy the very best one which fits your needs and budget.
