If it was me, I would not purchase a no name brand laptop, especially if I could not lay my hands on all of the specifications. One could end up spending (indeed wasting) a lot of their time trying to configure something that might, or might not, configure in the end.

IMHO its far better to pay more, and get a laptop with specific hardware that is known to work. I leave the exploring of brand new hardware up to those who:
a. have the patience to sort out the problems that will likely happen with new, possibly incompatible hardware, or
b. have the knowledge to sort out the problems that will likely happen with new, possibly incompatible hardware,
or
c. know of a back up approach that is perfectly acceptable, and won't leave one frustrated with a failed openSUSE (or other Linux) installation. In my case, neither a functioning WinXP nor WinVISTA would be an acceptable backup approach.

One has to place a "value" on one's own time. Now one can rationalize a certain amount of "wheel spinning" as well spent in training/learning, ... but there is a limit to this. I find Linux is complex enough without taking on the task of brand new hardware with minimal to no details on the various peripheries.

Show me a Mac user who doesn't check for Mac hardware compatibility first, and often I will show you a frustrated Mac user. IMHO applying a similar check for hardware compatibility first (before a purchase) applies to Linux (and if the compatibility isn't there, simply do NOT gamble). Looking at the hardware you mention, it occurs to me that this is a gamble.
