I finally joined. I got the universal plate, the silver milled case, Gateron Blacks and PBT DSA White Keycaps. I will get some nice LEDs and DIP Sockets and assemble it myself. This keyboard will be a complete rearrangement for me, because I have a full size, staggered mech with MX Blues and OEM Caps. I'm curious how these Gateron feel and hope I can use them for gaming and typing.
What size and type of LEDs and DIP Sockets do I need?

I'm going to make some assumptions based on industry standards and typical keyboard circuit design...
Regarding the LEDs, it looks like the Planck PCB uses 470 ohm resistors, so it's likely that you will need LEDs with a forward voltage (Vf) of about 3.5V-3.7V. This is, of course, assuming that the LEDs you choose provide your MAX desired brightness at 3ma . This is personal preference. Most resistors with a forward current (If) of 20 ma should fall in this category (manageable power consumption at 3ma x 48), but definitely NOT all. You'll need to make your own comparison of luminous intensity.
You must also consider your switch type. You mentioned that you purchased Gateron switches. These are known to have physical interference when used in combination with DSA profile and 3mm LEDs. However, Your OEM caps should work fine with 3mm flange-less (<--- important), but I would caution you to use something smaller such as 2x3x4 or even 1.6mm-1.8mm just to be safe.
The correct DIP sockets can be found at: LED basics: LED wiring without PCB: I use this vendor for both hobby AND work:

Thank you for your comment.
If I read that right I could use 3,5V 1,8mm LEDs even if I have DSA keycaps?

You got it!
