You don't need this VESA plate. This is for G24C that kind of model for VESA mount.
But you may need to buy the standoff for VESA support. Because the screw hole is under the back panel. You need to make then over the back panel by the standoff for the VESA mount, 100 x 100 mm.
I was considering buying a subitism heater a few days ago, but I was encouraged by members (thanks u/mofaha) of the sub to build my own instead. It was way easier than I thought originally and thought I could share some info for those of you that want to do the same.
An older post by u/GlossyBean (thanks, BTW) ultimately helped me to make the decision to proceed with the DIY. He was kind to post the links to the parts, but some of them are broken already. So I thought that’s something I can contribute with. It would be redundant to list the step-by-step because they are well documented on the KyaraZen's guide page. It really digests it super easy for you.
I got the parts mostly from Amazon only because I wanted them right away. They weren’t as cheap as on Aliexpress, but I didn't want to wait 30 days or more. So, here is the list of parts:
1- Clear mica : <Etsy LINK>
2- Textured mica: <Amazon LINK>
(I decided to use this one for the lower layer of the burner to hide the circuitry and give it a cleaner look)
3- Nichrome wire: <Amazon LINK>
4- Variable-voltage Transformer: <Amazon LINK>
5- Female DC connector: <Amazon LINK>
6- M3 male-female brass spacers, screws and nuts kit: <Amazon LINK>
Note: I know most people use a small drill to make the holes in the mica. I used an awl instead to avoid mica dust flying around. You have to be gentle to avoid breaking the mica, but it worked great.
