Is Newegg good for purchasing a PC to Argentina from?

Hola! My spanish isn't great, so sorry for the use of English. I'm reaching out on behalf of a friend I'm trying to help. Some pals and I were trying to get them a new PC build for playing games on, but Amazon totally screwed us and didn't send the prebuilt for months. An agent cancelled it today and apologized.

So... we're on the hunt again. Is Newegg reliable for buying a prebuilt from? Will it arrive/will customs give us much trouble, since the VAT and duties are pre-estimated into the purchase? Any help would be great. We'd prefer to buy it with our cards and send it to AR since AFIP might get mad if we send over the money + local purchasing would be overly inflated right now.

Thanks in advance!!
