No a computer is not a magnet. Most of the materials computers are made from (e.g. epoxy fiberglass circuit boards, copper, aluminum, various plastics, silicon, gold) cannot be magnetised. While certain structural parts of a computer are often made from steel, which can be magnetized they are not intentionally magnets.

Old computers (from the early 1950s to the early 1970s) used magnetic ferrite core memory as their main RAM and sometimes also as CPU register memory, but this has been replaced with solid state DRAM.

Computers have long used magnetic tape for offline data storage.

Since the late 1950s when IBM introduced the 350 RAMAC magnetic hard disk it has been common for computers to store data as tiny magnetic dots on spinning aluminum disks. Since 1970 when IBM introduced the floppy disk it has been common for computers to store data as tiny magnetic dots on spinning plastic disks inside a protective sleeve. However both of these are now being replaced by "solid state disks" based on Flash storage (a type of EEPROM - electronically erasable programmable read only memory).

So, even though computers have used some parts that operate using magnetism those parts are being phased out. But the computer itself is not and never was a magnet.
