Thank You everyone. I have a strict budget to follow regarding this system and I am not worried about compatibility or features as this system is expected to do very basic tasks.
For my current needs, I have finalized
Intel G630
Gigabyte GA-H61M-S2P
Seagatte Barracuda 1TB
Corsair 1333 RAM 4GB
Total: 12k, fits in my budget very well.
Kindly suggest budget PSU and cabinet.
Also one question, SATA III 6 Gbps is used only for SSD drives?
sata III 6gbps practical benefit is only for ssd because normal convention hdd can't even reach sata II speed.tambi is not a good option unless the usage is strictly htpc because of some serious lack of space.get any cheap intex/zebronics cabinet for ~600 & get a cheap psu costing ~650(avoid zebronics which is seriously lacking on 12V rail & get something which offers at least 20A on +12V which is mentioned on side sticker).
