hdd (not sure how many to get but this is the one im going with): https://www.ebay.com/itm/365031005984?
the part i have on hand that i will be using for the psu is just a basic hp prebuilt on since there will be no gpu. not sure how much ram i will need so ill need help with that. other thing im not settled on is the os so feel free to suggest one. got the case covered so im good on that. feel free to suggest some other parts or alternatives.
edit: lemme shorten these links...
