One of Acer's lower-end consumer desktops, the Aspire M3810 is a slim tower that ships with a very modest 2.5 GHz Intel Pentium processor, four gigabytes of RAM, a 640 GB hard drive, and an Intel X4500 graphics chip.
There's not much else to say about it besides the specs. The desktop has a typical brushed metal appearance; it won't catch any eyes but it won't offend the ones that notice it either.
They say desktop computers are on their way out, but Acer's still trying to tempt you with low prices. The M3810 is available now starting at $529, and it has a close relative (M3800) in a larger form factor for a bit less cash.
