It's not that it has an external power supply or that it's cheap that concerns me. In fact, the external power supply is a good idea . . . for a small form factor machine. This is a mini-itx system inside of a micro-atx chassis. The look and feel of the machine screams cheap Chinese crap. There has already been a ridiculously high failure rate along HP's consumer line (both desktop and notebook) for years, and it doesn't seem to be getting better. The fact that these systems are such colossal junk that HP is ripping their name off of them and selling them on the secondary market is enough to tell me what HP thinks of their customers.
Now, obviously, their business line is another story, or, at least, it was. Last year, I had the opportunity to conduct a little test. A customer of mine had purchased a couple of HP business desktops from their last tech. Then they contacted me to set these up and order a couple of Dells for other users. Now these are just basic machines running Office and a lob app called Shafer's . I didn't ask why they suddenly wanted Dell; I just sold them Optiplex 390's with the same spec as the HP machines. Core i3 (can't remember which chip now, but it was the same one as the HP's), 4 GB RAM, 500 GB HDD, Win 7 PRO x64, standard mini tower chassis. While setting these machines up, it just seemed like the Dells were going faster. So, once I got all the patches installed, I decided to see if I was right. I removed the few pieces of bloatware from both machines, and started the Office 2010 Pro install. I'm not kidding when I say this: the HP's took a full 3 minutes longer to install. Before you start in, I realize this was not a scientific benchmark. After a year of use, I still think the Dells run faster.
I will say this for HP: their business support is great. No problems at all getting parts or repairs dispatched. This goes the same for Dell, though I usually just do the online chat so I can multi-task. I truly hope the powers that be at HP get their collective head out of their ass and go back to basics. Good, reliable machines at a fair price, both on the consumer side and business side. And I keep my fingers crossed that the stupid things happening in other departments (printers, consumer machines, software, etc) stays the hell away from their servers.
