Zoostorm - most components are big brands (e.g. motherboard, CPU, hard disk). Generic memory usually, very cheap PSUs and very flimsy cases (which can be prone to vibration - mine has a thick manual on top to dampen it).
"and very flimsy cases (which can be prone to vibration - mine has a thick manual on top to dampen it)."
I have two excellent Zoostorm desktops (purchased from Ebuyer, quite sometime ago), and I would not quite agree about the cases being flimsy, because I find that they are no different to most cases on the market.
Agree though, that the cases are not a 'tank built' e-star type case, like a 10 year old self build I also use.
I have had my Zoostorm PC for almost a year now and have never had a problem.
I bought the basic unit and have put in a wireless qnd my old TV card so I can D/L TV, in particular recording videos to play on my main TV via my Chromcast Browser fitted to the spare HDMI stick on the back.
