Dragon 64 Computer - Rare  - Working but with issues (see description)

Computer works, however it has some issues - the power button has been removed but the computer is in "on" mode so when a working PSU is connected the Dragon will instantly power on and will only turn off again when the PSU is unplugged. The "H" key has broken off the keyboard (see photos). The plastic casing has changed colour due to being in sunlight, there used to be a round label stuck to the casing just above the keyboard which has left a round mark where the case has not changed colour under the label. The PSU is damaged/has the connector plug and mains plug removed so not sure if it works - I have tested this Dragon 64 using a working PSU from a Dragon 32 and it does work fine.
