[Elecraft] Recommended sequence for adding options

[PE3BB]

Hi all,

I started to build the K2. Can anyone recommend a sequence for adding the
options:
- k2 noise blanker
- k2 SSB
- k2 rs232-i/o option
- k2 Audio filter and RTC
- k2 antenna tuner
- k2 160m & 2nd antenna option
- k2 internal battery option?

I appreciate all input.

best 73,
