sorry for late reply...Wt about APC BR1500-IN? and pls suggest me a monitor too ( budget 12K)..
Never used it, but what is the pricing like for the same. Contact APC India and find out although I feel that the BR1100VA-IN should be enough for your RIG.
For the monitor, you can look at the following --
BenQ G2420HD ~11900/-
DELL ST2420L ~13500/-
Hope this helps. Cheerio!
