Steam Machine (Beta) Repairability Score: 9 out of 10 (10 is easiest to repair):

The Steam Machine is designed to be opened and worked on. The case is secured with a single Phillips #2 screw.

Modular design with off-the-shelf components makes it easy to remove and upgrade the hard drive and video card.

RAM removal is made difficult by the motherboard cowling, and may require removing the cowling.

During reassembly, precise cable routing is difficult without a repair manual.

Our Steam Machine is a prototype, but according to Valve, you'll be able to fashion your own Steam Machine out of any computer running SteamOS. Your mileage may vary, and future revisions may have different scores.
