great choices there guardian, a few others would be the compTIA linux + certification, the microsoft certified Processional one, and any of the apple certified technician one's... if you have the cash, good luck getting the apple pro cert though, it doesn't exist yet! lol

Microsoft Certified Professional (MCP) certification

Apple Certified Macintosh Technician
This certification is for the repair and diagnostics of all Macintosh desktops, portables, and servers. This certification is required to perform warranted hardware repairs for an Apple Authorized Service Provider. - Basically you need this one to order OEM parts for and make repairs on Apple products "officially".

there are a variety of others but this one above is probably the most valuable one
