@ Kilohertz, yup, looks like HDD failure. I guess you could send it to wei for repairs. I have an eMac with a blown transformer, since its only 1.2GHz, I'm gonna rebuild it as a PC

Yes, if they have the tool and skill. Deleted files can be retrieved. But it is subjective, not all recovered data will be in working form, some are partial or corrupted, but yes, can be recovered. If you are paranoid, you can do secure wipe with Disk Utility before installing the fresh MacOS. Before you click "Erase" button there's another button on the right that says "Security Options...", then you can select how many pass of zero-ing you want to do for the erase. The more zero write, the harder to recover your data. But this will also drastically increase the wear to your storage drive. As the process will write dummy data to fill up the whole storage, over-writing the previous record. Erase and repeat (should you select the more secure option). More write = more wear.
