First Build Advice

[CthulhusWake]

These are all of the parts I've picked out for it. Just wanting to make sure that they're all compatible together and that I haven't overlooked something else that I should be getting. Also, is there any area where I'm going overboard and can cut back, or any where I should go up?

looks good to me.
Though you have a 750W psu - which suggests that you are looking for a potential future upgrade - but your current mobo dosen't seem to support SLI?

now shop around for better prices:
microcenter
tigerdirect
amazon

Looks good... but you really don't need a 750W PSU for your rig.
If you are looking to cut back the cost maybe downgrade the PSU a little?
I mean, you won't even be using 750W with your rig, but if you want to keep the PSU there's nothing wrong with having an overly zealous PSU.

Antec case $50 Half the price. Just need to buy a fan for the front ($10 got me an Antec 120mm with a wired 3 speed switch that I don't mind hanging out the bottom of the front). I didn't bother with a side fan or a bottom fan as it doesn't get hot enough. Maybe later if I decide to OC. I also liked the painted interior.

MSI motherboard $150 a little more but it's a wash if you go with the cheaper case and it has a second PCIe 3.0, easy OC abilities to go along with your unlocked CPU. Maybe you decide down the line you want to get a second GTX 670? Look into the slot setups carefully and the speeds and compatibility first.

The PSU wattage is higher than necessary but nothing wrong with that, especially at ~$110. I splurged for a Corsair Professional Series AX650 for the modular cabling so that I could minimize cables though.

Might suggest a Corsair Force Series GT SSD over the Crucial. I don't know much about SSD's but the Crucial's write speed is really lacking compared. I was apprehensive about getting one because of quality and durability issues with SSD's but after looking around, it seems the Corsair was a decent choice.

CPU cooler? Planning on using the stock?
