Simrig modifications, specifically for simhub software and need advise

Introduction:

My current set-up:

• Aluminium extruded profile rig (with Simlab wheelbracket)
• Bimarco hummer seat (not sure if i like the comfort)
• T500 RS (+F1 add-on) with T3PA pedals (with analog brake mode)
• PS4-pro
• Logitec Z-5500 5.1 speakerset + Bose noise canceling headphones
• Benq W1700 4K HDR beamer on 90" screen

I mainly do PC2 and F1 2019

My desired set-up changes: (I would really appreciate it, if you can give me some advise)

• Computer (not a clue yet on hardware requirements)
• [optional] triples or VR. not made up my mind yet. all pending on the space at home.
• [optional] other seat
• [optional] other wheel, though I am not convinced yet that the DD wheels are worth my hard earned money
• Load cell pedals (i am having a hard time being consistent with braking, but i see that the V3's apparantly have tactiles that are apparantly supported by simhub) any experiences to share from that? and will it still work with my T500rs?
• more immersion by Simhub software:
  • Tactile transducers
    • Amount and placement : ?? Any advise?
    • Type : ?? Any advise? (i want to get some value for my money, buttkickers are to expensive to my opinion)
    • considering pedal rumble as well (std. in V3's?)
  • Wind sim (see that a lot of people use the Seaflo's)

I am just looking for someone who is willing to debate about the hardware mainly. I am at the point of spending a lot of money again, and just want to ensure that I don't purchase something stupid and want to make it worth it.
