I use an old Samsung syncmaster monitor for my secondary. And my main is an Acer SA230. The syncmaster is actually the first LCD monitor I've ever owned, it was purchased back in 2008. Would not recommend either of these for gaming, as they have pretty bad ghosting and response times.
Still bone stock cooling. Hasn't been a problem yet. But, it's definitely on the table for the next thing to upgrade.
Bought all the stickers from Amazon. I still have a lot left over that I didn't want on my computer. Not like they'd fit anyways. Regardless, I'm stuck with a lot of random stickers now that I have no purpose for.
