Summary: Unlike the previous review, you can upgrade/replace the power supply in this machine. It's quite easy and just about any power supply will work. There is very little "proprietary" about this computer, as it follows Intel design specs pretty closely.
Pros: Easy to setup and maintain. Simple case that's easy to get into to work on.
Cons: None that I can find. Though an internal USB port would be nice.
Summary: Great PC if you do not planing on upgrading. I am extremely disappointed.
Pros: Good, well built machine. Workstation ready
Cons: Proprietary, you cannot upgrade the power supply meaning you cannot add ANYTHING extra to the tower except 2 more drives. It comes with a low wage power supply that you can only purchase from this company. You CANNOT use any power supply according to the manufacture. This means you cannot upgrade...
Summary: The Dell Optiplex 9020 Micro business desktop shows that you can still have Core i7 power and full IT support in a mini PC that can hide behind a monitor. PROS + Compact chassis. + 8GB of memory. + Speedy SSD storage. + Six USB 3.0 ports. + Multi-monitor support. + Comes with Micro VESA mount.
Summary: Very good PC, fast and so very compact. Only the listing should have stated case size. As from the picture it looks to be a SFF (small form factor) case, but it is actually a USFF (ultra SFF) which in my case ended up be perfect.
