It seems to me like a waste of money.
I grow in a pc myself - its my vegitative growroom.
Setting it up was pretty easy - gutted out an old PC case I got for free from a "recycling" facility, cut an intake hole in the bottom of the front of the PC, made it lightproof (kept one metal plate that was in from of that intake and painted it all black so light will be caught), put astro-foil (kind of mylar foil) wherever possible, put 1x45W CFL in Daylight color (6500 kelvin) with a timer, built some carbon filter and fixed a big PC fan and thats my air outtake.
of the "wall" that blocks light I've fixed 2 minimal fans to move air around.
All of that took only sevral hours of work, mainly because I was lacking tools.
I've successfully flowered a male plant in there (changing the CFL to a 45w WarmWhite - 2700k) and it works great for now.
Unlike the ready-made thing I:
1. Saved money.
2. Haven't let anyone proccess the order, gave no-one details and so on.
3. Got more light - the 240$ thing have 4x16W lights, which is more space taking and less efficient. Or should I say was able to customize whatever I wanted.
4. Got an odor control that is way longer-lasting and efficient.
5. Got stealthier as all of my meters are inside the case, unlike this PC which have a LCD screen that showing stuff.
By the way, I'd recommand growing at least 4 plants in such a thing because you need them compact anyway and growing one very small plant is a waste of space.
You can go SCROG and tie it with a net, but thats more work and longer vegging.
