Quantex Microsystems was a direct-PC manufacturer based in Somerset, New Jersey, founded in 1984.

Although it never matched the sales volumes of the largest PC retailers, their products met wide acceptance by customers.

It filed for Chapter 11 bankruptcy protection on August 17, 2000, when its key supplier, Fountain Technologies, who also supplied computers for the Pionex, Inteva, and CyberMax brands, filed for Chapter 11 bankruptcy protection.

The attraction for many was that Quantex combined high build quality, great technical support (before the financial trouble), brand-name components and above all lower cost than most rivals.

The UK operation continued for several months after the US company declared bankruptcy, and were easily contactable during that period.
