Minimum configuration starts from Celeron-400 with 128Mb of memory. If you would like to use it as a file server, we might need to replace your old hard disk and add a new one for a backup.
UPS (Uninterruptible Power Supply) is required. If you have an old one, we might be able to repair it or replace the battery.
