This was originally suppose to be a $500 budget build that went a little over budget...but can't complain too much since I got some good deals.
CPU - I didn't even considered Haswell when I planned this build but the FX-8320 that was on sale for $100 was sold out at MC and so was the i5-4570k. I didn't wanted to leave empty handed so I went for 4670K.
MB - It was bundled with the CPU. After taxes and rebates, it came out to $32. Not much more to say.
Ram - Another bundle deal. This time with the GPU.
Storage - I pick the Seagate because it was the best bang for your buck. Can't imagine doing another build without a SSD. The 1TB for extra storage.
GPU - This is actually a huge overkill for me since I'm not much of a gamer these days but the price was too good to pass up.
Case - I was originally going for the Corsair 200 but heard great things about Fractal and it was on sale without a rebate. The case is awesome but now I kinda wish I got the R4 for a more quieter build.
PSU - I wanted a modular PSU with good enough headroom for future upgrades and this fit the bill.
Heatsink - I don't know much about heatsinks but I figure something this popular can't be bad. Installing this was definitely the hardest part of the build. I'm pretty sure I did it wrong and put too much thermal paste but the temps still look good. CPU idles at 25° and 70° at full load w/Prime. I'm currently OC'd at 4.2 GHZ w/ 1.085v. I'm not totally convinced that it's stable since I haven't stressed it overnight but I did ran a bunch of test and so far so good.
Overall, I'm happy with my build. Its been 5 years since my last build and this one will probably last me another 5. The only downside is I'm running out of things to tinker with.
