The other issue is that modern Web applications bloat up memory use. I'm not even sure that 8GB will be enough.
Several years ago, I had a desktop machine with 4GB of RAM. If I opened Chrome with around 8 #JavaScrippled tabs, it could freeze my X11 session or even force reboot the computer in about 8 hours. Even though I'm sure Chrome and Chromium have improved, they are probably still really heavy on RAM usage.
I didn't look at the price / MSRP, but as long as you're sure that OpenSuSE will install and that 8GB will meet your needs, you're probably not going to find anything that is clearly better unless you're almost willing to double the price. I'd say go for it.
