Rate my planned specs (First Build)

[ArtificialApple]

Hello all,
I have decided to switch to PC gaming this console generation. I have taken basic classes on computer building, but I don't know too much about part shopping. Here are the parts I plan on using. If you have a better deal or a better part suggestion, please reply. My budget is $800 maximum for the actual computer.

EVGA SuperClocked 02G-P4-2765-KR GeForce GTX 760 2GB 256-bit GDDR5 PCI Express 3.0 SLI Support w/ EVGA ACX Cooler Video Card


Intel Core i5-3330 Ivy Bridge 3.0GHz (3.2GHz Turbo) LGA 1155 Quad-Core Desktop Processor Intel HD Graphics 2500 BX80637i53330


NZXT Apollo Black SECC Steel Chassis ATX Mid Tower Computer Case


Western Digital WD Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model BLS2KIT4G3D1609DS1S00

Rosewill Stallion Series RD700 700W ATX12V V2.3 SLI Ready CrossFire Ready Power Supply


Rosewill Stallion Series RD700 700W Power Supply

GIGABYTE GA-B75M-D3H LGA 1155 Intel B75 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard


UPDATE: Thanks to everyone who replied. I liked Maurelie's suggestions so I may go with those. I do have one more question: how do I pick a case? Do I need to do all the measurement math as far as the part components go? I'm new to this kind of thing so bear with me.

Fine upper mid range build, I would though swap the PSU to something like XFX core edition 550watt or similar that would be plenty for the system.

The only thing I'd necessarily replace there is the old Rosewill Stallion. While a few notches better than "junk," by today's standards it is obsolete. Your system will run well on a quality 500W PSU. I'd recommend Seasonic, Antec, or the new Rosewill Capstone.
A 1TB hard drive won't be much more expensive than the 500GB model.
Make sure the RAM will run at 1.5V. Otherwise, I'm not inclined to niggle; the build will do well.

These parts look good, forgot about the optical drive. How would I go about choosing a case for these parts? What criteria need to be met?
