I would be careful about the heat on a tank of that size the MH put off a good amount of heat. An electronic ballast will reduce the heat pretty significantly. I would probably recommend a pendant for that size tank so you can get a little distance between the bulb and the water to allow some air to disipate the heat.
PFO has some very nice DIY type stuff. Usually just requires assembly. I don't think they have an electronic ballast.
