eCommerce Customized Computer Shop

I have been looking at several eCommerce plugins this week and I found wooCommerce. I like it but I have so many variations of each computer model, it is getting time consuming to get all the variations uploaded. I tried to import a csv file and it was going well but still very time consuming.

Basically, we are starting to sell custom computers online and we need to have multiple options for processor, memory, graphics, and a few other categories. Each option would change the price as well.

wooCommerce does this but takes way too long to get everything in there. Is there anything that will allow be to have this, it would be like if you were to build a computer on a website like Dell.
