Well, you could use MyBitcoins gadget, but if you want to show LTC price I recommend that you download my MyLitecoins gadget from http://domchi.cc/mylitecoins/ - the functionality is the same, but the design is different and it comes with Litecoin price already set up - although it retrieves the BTCLTC price from Poloniex. To set it up to show LTC price in USD from Bitfinex, change the following settings:

Bitfinex
exchange URL: https://api.bitfinex.com/v1/pubticker/LTCUSD
exhange rate JSON key: last_price
ticker currency: USD
field 1 JSON key: ask
field 2 JSON key: last_price
field 3 JSON key: bid

Make sure your logic board can support PCIe cards in ALL slots. Some share bandwidth in such a way as to effectively disable certain x1 slots when the x16 slots are filled.

I've learned this the very hard way by spending quite a lot of money on what I thought was a good board with 5 slots - 5 extender cables and GPUs, only three of the GPUs are being recognised. I'd check first - certainly before butchering your case (if it's a nice case)...

And remember that GPU cards always seem to run cooler *outside* of a case than inside. Even without box fans etc. my open-frame rig is cooler than the case boxes.
