I am a fairly advanced computer user that has built my own systems and I can do all my own hardware replacements/install, etc, but I am thrifty, too. I like to game a little (old-school RPG mostly, some shooter), and I listen to a LOT of music. I also regularly work with 120k+ word RTF files, which anyone who has done that knows can seriously drag down some computers.TL;DR on this system? BUY IT! You won't regret it!This machine is an AWESOME value. First, I got better than was promised in the item description, and the computer is spotless inside and out. The exact model I got was an Optiplex 7010 with i5-3570 at 3.4ghz, a tiny little bluetooth/wifi USB plug that works MUCH better than the onboard bluetooth/wi-fi in my last system did, 2TB hard drive, 8 GB memory on four sticks, and plenty of interior room to add more drives or a graphics card later if I decide to. The power supply isn't impressive, but I can upgrade that myself very easily and cheaply if I decide it needs it. Right now it works perfectly as is and right out of the box it has plenty of speed and power to run a graphics-heavy game like Dragon Age or edit a 200k word file, and I'm getting great sound with my music, though I may yet tweak the sound properties a bit to coax a little more volume out of it. My old system was obviously louder with the same music program (WinAmp) and speakers (Logitech) playing the same songs, but that is absolutely the ONLY thing I have found that isn't excellent.Overall, this is an amazing deal!
