Wait a second, she doesn't actually have to have us physically build it...
What Pippa could do if she wants to- actually, fuck it I don't want to type this out in hypotheticals give me all the med reacts you want.
Pippa. Don't go and buy another pre-built computer, buy a new laptop cord and stream with that for a little while. Use those streams to make content out of building a PC. Have a few streams where chat helps you pick parts and you react to part reviews, and so on. There are free websites that let you compare pricing on parts and check their compatibility. There are people in chat and Discord and certain shady forums who are willing to help via donation, advice, and often both, to make sure you can get what you need, and people will be more invested in the streams because it will be a computer that the community is helping build for you. When the parts are all picked out and have arrived, ask someone (Sleepy is already potentially willing to help, apparently) to help you build it in an offcollab. If you ask, the community is ready to be there for you in your time of need. No one wants you to be hurting over scummy companies ruining streams for their pound of flesh.
Seriously. I will help buy you an actually decent computer, rabbit.
