any other places to earn points to redeem for games?

Of course :-)
There are multiple ways to earn ARPs. The most easy:

• log in every day (there are rewards for each day, and for each consecutive day)
• do the daily tasks (watch twitch - or idle it, of course - and the changing daily, which can be clicking on a social media button [no real social media action needed], replying to a forum thread, opening news section, etc.)
• weekly steam quest, you just have to have recorded play time (1 hour) for the featured game(s) of the week. Usually 2 or 3 games (each one gives ARP), al least one is a free game that everyone can access.
• once a month, the daily login reward is not ARP, but a "booster" that you keep for future activation. When you choose to activate it, your ARP earnings will be doubled for 48h. Best use of it, in my opinion, is to activate it on sunday afternoon : you can do the weekly steam quests (idle time - you can also prepare it during the week, so you have only a few minutes to add to each game playtime) with double points, same for daily twitch. Then the day after, monday, you have the new steam quests, so you can do it again. And you also have the tuesday morning to watch twitch with booster still active
  Hope it helps !

Absolutely... NOT :-)
To my knowledge, Alienware makes high-end gaming PC. I build my PC myself since 25+ years so I never bought any hardware from them, and probably never will. They are a Dell brand. I don't know if they make standalone peripherals.

For me the most pain in the gamehag was that they take away your points after small time of inactivity it's stupid. First they earn from you then steal the points ...

Sure.
