So I ordered ram with 2 day shipping and they are shipping the ram like 1 hour away from my house and it takes them 7 days normal or 5 working day and there is still no guarantee I’ll get it tomorrow (I DID 2 DAY SHIPPINNG I’m mad) so what if I build the computer and put the ram when it arrives and ik I can’t turn on PC without ram idk if it will work or not but I’m not so can I build it and just install ram as soon as it gets here or should I just wait
