There are 2 types of Vantecs, there is the standard one and a mini one. Satan's Mutt (and I think Ploughbot) use the mini version designed for High power FW's/American LW's. The Vantec for sale is the HW version.

The case/heatsink is on most speedo for a reason, it's not advised to remove it.

I suggested the botbitz 85a controllers for 2 reasons: 1: If you bought them now then you wouldn't need to upgrade your speedos if and when you upgrade to Speed 900's, and 2: I don't like Electronize speedos :P. I've seen a fair few broken ones with the relay broken, and their response is far too slow for my liking.

Electronize will drive 4 drills (see Tormenta), but to save a bit of money in the long run to buy botbitz 85A ones. Just my opinion.

Oh, BTW, the shipping and tax ordering from Australia (botbitz) is far cheaper than ordering from the states for whatever reason.
