Maingear revamps Solo 21 AIO, now fully upgradeable, starting at $899

Maingear released their first all-in-one PC only five months ago but they’ve already taken it upon themselves to completely revamp the system from the ground up. The updated Solo 21 AIO has a new look, new hardware and a cheaper starting price but more importantly, it's fully upgradable and compatible with Thin Mini-ITX motherboards.

The latter helps to ensure this simply won’t be a one-and-done PC. Instead, you’ll be able to upgrade the system down the road when new and more powerful hardware is released. That alone is reason enough to give the Solo 21 AIO a serious look in my opinion.

Aesthetically, the Solo 21 is certainly one of the better looking AIOs to hit the market in recent time. The system ships with the stand seen above but there’s also a a VESA mount option should you want to install the computer on a wall.

An entry-level Solo 21 contains an Intel Core i3 2125 CPU clocked at 3.3GHz, a HD61AG Thin Mini-ITX motherboard, 4GB of Corsair DDR3 memory, Intel HD graphics, a 500GB Seagate 7200 RPM hard drive, an 8X DVD burner and Intel Centrino Wireless + Bluetooth – all running Windows 7 Home Premium 64-bit.

Note that this configuration doesn’t ship with a keyboard or mouse and you only get a Sandy Bridge processor. $53 more gets you an Ivy Bridge Core i5-3450S, a worthy investment if you’re already dropping down $900 for a new computer.

Maingear’s configuration page shows an estimated shipping date of September 7 for Solo 21 AIOs.
