OK. so final:
You say you can move the motherboard with the CPU still in. So leave the CPU and the cooler still attached to the motherboard when moving? (and this way dont remove the thermal compound?)
When you say don't work on carpet could you clarify: I was planning to work with the case on my wooden desk cleared off other stuff (speakers, phone etc. and therefore the case won't be on carpet). But in that scenario would be standing on carpet.
I also have a Antistatic wrist strap, that'll cover for touching metal case/psu right? (just in case I forget). Oh and I don't need one strap per wrist if I read correctly?
I must sound really paranoid
got 3As in A level, so apparently i'm only clever on paper haha
