The build itself was relatively painless, the audio header was (surprising i'm sure) a bit short but it fit after i cut a zip tie.
I know the overclock is conservative, but i had trouble convincing it to boot at anything besides 4.4Ghz @1.2v, so i ratcheted it back some and found a good voltage and temps i was more comfortable with. (If it seems i am screwing this up, please tell me, this is my first time to overclock.)
CPU: i am either overclocking very wrong (which is quite possible, but i'd like to think i did my homework) or i got one of the worst haswell chips out there. but 4.2GHz is still about 24% better than stock clocks, so it's still an improvement.
CPU cooler: I knew it had a white LED on the fan going into this, but the thing lights up my entire bedroom. Still, it's a lot better than stock, which I was running for about a day.
Mobo: Feels very sturdy; my only complaint is that the software bundle is incompatible with windows vista, which I was running while waiting for the os to ship. Still, that is very minor so i'm still giving it full marks.
Ram: I didn't realize it was low voltage when i bought it (ebay). I had to manually adjust the voltage in bios, but besides that it's RAM. it does ram-y things.
SSD: Worth every penny. It goes from the gigabyte splash screen to log-on screen in 15 seconds.
HDD: I am loving the caviar black, it's more space than i really need and faster than any other (traditional) storage that i've ever used
GPU: it's a lot nicer of a card that what i was originally looking at, thanks to newegg sales, but it has some coil whine (only on lower graphics games) and the pcb is blue.
Case: Love it, it looks sleek, and it was amazing to build in.
Fan: For whatever reason I thought I could put the back fan in the front of the case (they are different sizes, I know now) and use this in the back for better airflow. that didn't work out. but the colored ring is cool, right?
PSU: It's well rated, well reviewed, and it came with far cry 3. but the flat cables are sort of annoying, not to mention the cables for the gpu are so short they are pulling the gpu down slightly.
OS: I got this upgrade through microsoft campus agrement but i had to wait for it to arrive, leading to a long wait for the computer to become ready to use.
