i was thinking of getting gigabyte c200 glass does it have good cooling if not, tell me a good case with good cooling psu shroud needed.
gigabyte c200 glass or Antec NX310Cases are ~10% compatibility, ~90% personal preference.
Pick something that looks good to you, and will fit your components.
Typically, anything geared towards "glass" will not have particularly great cooling.
What options are available to you? Website listings are limited for India.... cheapest I can even find for a TG case with PSU shroud, is ~4,800 Rupees.
