Is this enough to play farcry2, gta-IV,modern warefair-2 type of game without gpu & power supply ?
You should have told us straight away that you're interested in a gaming PC.
-> The Intel HD Graphics IGP that comes with the
i5 660 is not powerful enough to run games like Farcry2, CoD:MW2 or GTA-IV.
It does OK with 2D games and other PC applications like movies, email, web browings and office tasks, but not 3D gaming.
A power supply is always necessary to get the new PC run. For a gaming PC you need one powerful enough for the gaming video card.
For a GTX 260, a HD 4850 or HD 5770 video card you need a very good 400W PSU or an average 500W PSU. The PSU you get with a case like you have listed above is probably going to be a less th an average PSU.
When you look for your case get a PSU that's powerful enough to run a future video card like a HD 5770.
* Because you want a gaming PC and you're on a tight budget I really think you should look at an AMD CPUs and motherboards. Going this way should get you into your good video card sooner.
-> Look for an AMD Athlon II X3 435 Rana or AMD Athlon II X2 245 Regor CPU.
-> AMD 785G motherboard. It has integrated HD 4200 graphics - not powerful enough for 3D gaming but will do everything else. Some examples:
BIOSTAR A785G3 - BIOSTAR TA785GE 128M - ASRock A785GMH/128M ASRock A785GXH/128M - ASUS M4A785-M - MSI 785GTM-E45 -
or AMD 770 motherboard. They have NO integrated graphics so you must also get a graphics card. Examples:
ASUS M4A77D - ASRock M3A770DE - ASRock 770 EXTREME3 -
