I'm personally not sure about the filtration, is it UGF?
I would also be wary of the lighting, the cost and availability of replacement PC bulbs might be an issue.
If I were to buy something like this, I'd be treating it more as a tank and lid, not a complete solution. I'd be expecting to do something about the lighting, maybe retrofit LEDs or use spiral CFLs. and I'd be looking to use a more traditional filtration method, either that or possibly a mattenfilter.
But if you think it's the tank for you, or you're still not sure, there's more info and more pictures and a price that's $5 cheaper directly from TruAqua (They have other tanks and kits available too).

I have personally ordered from them in the past and was happy with their service, my order shipped quickly and packaging was creat.. which is somewhat important with glass aquaria.
