One of Acer's lower-end consumer desktops, the Aspire M3800 is a standard-sized tower 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 M3800 is available now starting at $450, and it has a close relative (M3810) in a smaller form factor for a bit more cash.
