I’m not Shane, but my specs for a DIY computer, built in early 2015:
Intel Core i7 4790K 4.4GHZ (Haswell)
Cooler Master Cosmos II XL-ATX Ultra Tower Case Black
ASUS Sabertooth Z97 Mark 2 Motherboard
G.SKILL RipjawsZ 4X8GB DDR3–2400
EVGA GForce GTX 770
Western Digital SATA3 2TB
Sandisk 256GB SSD
Mionix NAOS 7000 Optical Mouse
Corsair K70 RGB Keyboard
I’m running a dual 27" monitor setup running on Debian Jessie with i3wm.
These specs are pretty much top of the line for late 2014/early 2015, and it cost the exact same as a brand new Macbook Pro (about $3000 CAD). Parts were all sourced from ncix.com.
It doesn’t take a huge amount of know-how to build your own computer. Just some research and shopping around for good prices on parts.
