Great looking case with lots of features for an excellent price. The dust filters are easy to remove and it's good to see that they included one for the top as well. The LED is nice as most cases in this price range usually don't have it included let alone one that can change colors. Building in this case is super easy and clean looking thanks to the velcro straps and the PSU shroud. The only negative I can find that may bother some people is that there is no top radiator support. Excellent case overall and I would highly recommend it.

Really fun case to work with, and quite beginner friendly.

Nice design, good cable management options, and has rgb lighting. I bought this off of amazon for $70 and two days after the price dropped to ~55. That pissed me off.

Great case, nice lighting options, very easy to work in. Space is a little limited at the top, so no top-mount radiators (at least not easily). Besides that, it's a fantastic mid-tower!

Looks good and does it's job. Cable management with a non-modular PSU was perfect. The interior looks clean and there's room for two or three more fans in the future.

Good, but wish I'd known about the P300 sooner!
