It's kind of a crap shoot. The quality isn't always the best. I installed 2 into non-gaming computers. One was an obsolete build being readied for give-away to distant family member. Put the wireless card in the back (PCI slot) and didn't have many problems. The second box was more modern but still on the older end. Totally different hardware and about a generation and a half newer. However that was a lot harder. There was some stupid hardware incompatibility where the PCI slot used would dictate if the card functioned or not. And when "not" it would stop a lot of other things from working properly too! I managed to find a slot after a lot of effort uninstalling, reinstalling, reviewing online reviews (that's a redundant thing to say!) and so forth. It works now on that wireless card. The one I bought had the best reviews of its price range too. Most were downright abysmally bad. This one, the best of the lot, was 60/40 chance of working.
Basically unless you're willing to schill out tons of cash the lower end ones might or might not work.
Do all the research you can ahead of time and don't throw away any packing or receipts. Be prepared to RMA it if it just won't work.
