As part of building a HTPC for myself, I have roamed about in Ritchie Street in Chennai extensively and and made a few calls across the country. Conclusion - HTPC cabinets are NOT available in India. Only Antec has a model available and they are very evasive when I speak to them. ITDepot, who are the dealers for Antec have no idea about any HTPC cabinet. I am not sure what is available fro iBall.
There are a couple of companies that make decent HTPC cabinet. Zalman (::: ??? ??? ??? ?? :::) is one but is expensive. Silverstone is another. They have over 15 models ranging in prices. I have shortlisted 4 models
GD01B-R - S$248 (~6000Rs.)
LC13B-E - S$228 (~5500Rs.)
LC17B - S$219 (~5300Rs.)
LC20B-E - S$339 (~8200Rs.)
All these have 8 or 9 bays, 4 to 5 fans/fanbays for cooling, 7 expansion slots, and connection for USB, IEEE, Audio, and MIC. The GD10B-R also has a 52 card reader built in.
Silverstone has four dealers in Singapore, and Prolink Data System have all these models. If you know someone travelling to Singapore, it makes sense to get one of these cabinets. Please check SilverStone Technology Co., Ltd - Designing Inspiration for details about specs and their dealers in Singapore. Most of these models are award winners and would look great in an HT rack.

I am going through the same pain now. Hunting around for a slim pc case for the last 4-5 weeks with no success. BTW, theitdepot.com shows some silverstone cabinets. So, you may be able to get it from them.
I am now trying to get a relatively small coolermaster cabinet and get my pc assembled.
