I run a computer service biz and most Acer products I have come across were pretty decent, I expected more from this for the price.Upon opening the box, the WIRED mouse and keyboard struck me first as pretty cheesy, but I could have lived with this.It's a pretty big case for what turns out to be more of a thin client or a laptop in a case, but the space is wasted since you couldn't put much else inside it anyhow. There is a provision for mounting extra hard drives, but there's not enough power supply amperage or plugs to connect two more drives.The worst part is the power supply, it isn't a standard ATX power supply; it's one of those half-size proprietary units with non-standard plugs to interface with the motherboard. Power supplies are one of the most common failure items in a computer, and if this one goes you won't be able to replace it with a standard ATX power supply. The plugs on the motherboard won't work with a standard ATX power supply, and there aren't any mounting points on the case for a standard ATX power supply.The motherboard is also a large part of the problem, as it doesn't have a standard ATX power supply connector. It has an extra PCIE slot for a video card, but the power supply doesn't have any power connectors for the card.I liked that this has an optical drive, but it's a laptop drive that's been modified to work in a PC case. The power supply connector isn't a standard SATA power connector, it uses a modified plug on the non-standard power supply.This unit has a decent feature set and specifications, so if you don't ever intend to upgrade or do any gaming, and you know you'll have to throw it away within two years (usually right after the warranty has expired), then you could do well by this, but it isn't anything more than a disposable appliance.
