You could play the game on a toaster if you wanted, it's requirements are rather low. Any off the shelf pc or laptop should be able to run the game at marginal settings if it was made int he past 5 years.
As far as your gear/acocunt, SE used to say that they were deleted after a period. Never had it happen, though, so I'd log in and check. You should be able to see your stuff before you reactivate your account.
