It’s OK, but wait for Ryzen, then make a decision on CPU /mobo. Also, noctua or cougar vortex for good case fans. Look at AIO for CPU if you want. Look at a 480-512GB SSD on sale!!! Also look at a SSHD. Writes and reads much improved over conventional hdd!!! Wd blacks r OK, but firecudas r much better.
SHOPDEALs to save money on build!! EBay has good deals on new and used items too, with a 30 day money back guarantee.

But good build options. Honestly, you could go mini itx if only using a gpu. That would make it console sized and a power house, otherwise case could become old and bulky. But make sure that you have 1 to two slots that are open for memory upgrades. Otherwise, they’ll cost more when you need to upgrade.

first id get the k varient but also for now just wait for zen and if ur still settled on the 6700k it will probably be cheaper
