Getting access to a wide range of test PCs

Are there any companies/services which will let you get remote access to specific hardware? Developing games, you need to test on a who battery of hardware combinations - CPU/GPU/OS/etc and for a small company that's pretty impracticable. So say I want to test on a Core 2 Duo + nVidia 8400GS... or even on a certain model like a Dell Vostro 1234... do companies sell remote access to allow outsourcing the hardware in this way?

If this is better on another site, plea开发者_C百科se say in a comment rather than just close-vote! Where does software testing belong on SE anyway?

If you're looking for a variety of systems, why not release a public beta? I can think of no better way to run the software on a wide range of hardware configurations.
