Nice build but 16GB of RAM is only $20 extra. There are $230 dual fan 1660 Supers, also that evga gd 500 PSU seems nice for $50 despite being non modular. Why opt for modular anyway when the case has PSU compartment where you can hide extra cables (it's only 2 cables too) and you don't have to worry about losing any of the them. That's $30 saved or $709 in total.
Article was written 7 days ago. Prices change and part availability changes. Something to keep in mind.
As for the 1660 Supers, I have written this article 4-5 times complete already, due to the 1660 being replaced by the 1660 Super,certain versions going out of stock, other parts going out of stock, Mail-in-rebates influencing prices etc.
Its also not an article telling you that you MUST BUY THOSE PARTS. It is geared to give users a rough idea of what they should be looking at and to start as a jumping off point as no system is one size fits all. Thus getting the community engaged and actively looking at ways things can be improved.
as noted above by
@ShurikN one could drop the capacity on the SSD to bump up to 16 GB of memory.
As for the EVGA GD500 havent seen any actual reviews of the unit thus far considering every manufacturer seems to have good and bad units. Even the Corsair unit is what I would consider passable / decent for an entry level build. That said, would something better be nice? definitely.
As for modularity who said anyone had to go with the Phanteks P300? article clearly states chassis is very much a personal choice, not all cases have ample cable routing. Modular is a must in those situations. Therefore fairly decent entry level unit with a solid warranty and modular cabling was selected.
When writing the article Amazon did not have the GD500 in stock or listed. It is a new unit for them (newegg has had it in stock for awhile at least). that said depending on the quality its a viable alternative and the article can and will be updated. However, i would prefer to see a proper review of its internals first.
Just because its 80 Plus Gold and has EVGA on it doesn't mean its good same goes for other major brands. But yeah if its a solid unit internally, Id gladly update the article with it.
