If by the highlighted part, you meant in a way that the choices that you get are compatible with each other, then I believe "
newegg's PC builder" only shows you compatible choices if you choose your components starting from the top, then simply add those to the cart and pay with
BTCitcoin.
- Having said those, they use BitPay as their payment processor [unfortunately].I swear by Newegg, though I have had problems with BitPay (although I have to take some responsibility for that). One thing about them is that you can only pay with bitcoin if the item is sold by Newegg, so keep that in mind if that was your intention OP.
I'd imagine they'd have everything you'd need, and they ship very quickly too.
