Need recommendations

[Rational.Person.]

Budget: $1300
Intended build: mATX build for my friend, something that satisfactorily runs Crysis 3. Usage: General work, some shooter games, no need SSD or monitor. Need OS and keyboard and mouse and speakers. He prefers a rather colourful casing, that's why I'm looking at the CM 344...
Intended build:

MSI B75MA-P45 + i5-3470 $344
KVM DDR3-1600 CL10 2x4GB $76
PowerColor HD7870 Myst $328
Seagate 2TB $117
Seasonic M12ii 620W $125
Cooler Master 344 (mATX) $55
Windows 7 Home Premium 64Bit OEM $120
LG 24X DVD-RW $25
Logitech MK200 $25
Altec Lansing BXR1220 $29

Total: $1244

Any suggestions?
