Da Vinci 1.0 AIO, Looking for upgrades and suggestions

Hello all,
I've been lurking on this forum for some time now, researching the most I can on this printer. A lot of you have been extreamly helpful so I thank you all for that!

I want to start off by saying 2 months ago I found this printer in the trash in some rich neighborhood while doing a new construction. The damage wasn't overly bad but there was quite a bit of things I had to fix. Luckily I havn't spent a dime on anything as im a horder apperently according to my wife.

Anyways, For the past two months I have been constantly researching any upgrades. The repairs I have done to this unit, I have managed to get it working in operational order. So now im on the last stage for it to make clean prints.
The Heat bed is warped and the glass is chipping. I removed the heat film and fipped the glass to get it going for now however, it will not calibrate through the machine due to the bed being warped. I have to manually make some test prints and adjust it with monitoring the prints to get the closest level as I can.

So today, I am here asking for some further advice. I have found some old threads about alternative upgrades for various components. However, unfortunately those threads are quite old and pictures are no longer current or active.
I am hoping you all can point me in the right direction for some current upgrades I can do to this printer such as the following;

• -Cooling designs or suggestions

• -Replacement upgraded extruder

• -replacement upgraded Heat bed and glass to support 200x200. (I know I could just get glass but id rather get something more suitable. Besides the OEM parts on this printer is quite garbage)

• -Any other useful and admirable upgrades or suggestions would be helpful as well.

• -Upgrading the firmware to run repeater would be ideal however, When I found this unit it was already on the latest firmware so I dont think I could downgrade it without having the original dumps. (Basing knowledge off old mod chips on other things) I hope im wrong here. Correct me if I am please.

Thank you in advance!
