Hey, welcome to OCN. Pretty sure you got close to the right section since you didn't specify if you were going AMD or Intel. I will use newegg for all components, but if I were you and lived close to a MicroCenter, I would HIGHLY recommend going there to get your case and CPU/Mobo combo because they give $50 for both bought at once. Cases are price as is and no shipping, newegg has some options, but I won't be recommending anything that charges shipping to make that equal with a brick and mortar store.
I'd recommend going with these components: all conveniently hyperlinked for youAMD CPU/Mobo ComboIntelIntel Mobo
use the promo codeGPU: 7870 Tahiti LE
cheapest price/performance with current rebate
$50 with current promo code, if you buy after tomorrow just get whatever you likeSSD (optional)
(not the cheapest, but insanely reliable)PSU
$12 off promo code good for today onlyPSU
(if after 3/20)Case w/windowCase w/o window
(I've personally built in this case and it is fantastic)
Total prices: Give or take $20 on promo codes and whatnot....
AMD combo build w/o SSD and before rebates and the $12 off PSU: $692.94
AMD w/SSD: $801.93
Intel w/o SSD and $12 off PSU: $732.94
Intel w/SSD: $841.93
There ya go. Best of luck. No Operating system price included since there are options.
