Not a PC, laptop, but serves me better than any other PC I've ever had.
I'm actually impressed with what it can run, it has amazing speakers and I'm not embarassed to say I love my dear half-gaming laptop (not to insult those who say there is no such thing as a gaming laptop )

Mouse: Logitech, not sure which model, nothing special, but does the job as it's supposed to

Btw, they say arena is worth it around third win, and once you learn which cards to pick, it's partially luck (on which cards you get), but it's entirely possible to get to 15 wins.
I myself don't play arena since I get very nervous if I get something like 1-3 or 2-3, so my record was 8-3 I think, but out of maybe 10 arena games

Also, I got golden Malorne on my first account, figured it's not that good, I better disenchant it for something worth it.
Created Ysera, got Ysera week after. I cried

No goldies on my new acc yet though.

Btw, as someone sad, in 20 boosters you should get a legendary, but still, it's not a must.

100% for one rare, 20% for epic, 5% for legendary, 0,5% for golden legendary (idk chances for rest of the goldies)

Let me update on this:
I got so frustrated these days!
1. First turn Alexstraza!
2. First turn muster for battle + hero power + quartermaster (I mean wtf....)
3. Ragnaros raping, I don't even want to mention it....

I got a chance to pull out some nice combos, however, I don't have such an admirable collection, all the legendaries I've collected so far:
Jaraxxus, Prophet Velen, Nat Pagle, King Mukla, Mekgineer Thermaplugg, Old Murk Eye (Achievement ofc).
I've had an account before, but since my GF started playing, I didn't want her to quit after seeing how shitty HS can be if you don't have any good cards, so she got jaraxxus, mukla, mekgineer, troggzor, ysera, deathwing, grommash, murk too, malorne, archmage antonidas and many more+ plus whole naxx.
I bought myself first wing of blackrock the other day, and tbh, one of the best investments in hearthstone (I've unlocked whole naxx without paying on my old acc, I don't know how the fk have I been so patient).

Anyway, in the last week, I've never got so many shit boosters.
First of all, I think I've got my 85th bomb lobber, I so hate that card for getting it so many times, I don't even use it!
My usual rule is, when I get a legendary, next 20 boosters aren't worth crap, I got so frustrated once, I went to blizzard's FB page and gave them a hard time about it lol.

I think it's time for me to take a little break, I can't believe out of 5 boosters I opened in the last three days (one watch and learn, brawl and rest quests) I've got one card I didn't have: Bomb Lobber. And that's only because I disenchant him every time I need something. FML
