from completed build I made this!

I love the aesthetic of the case. Everything fit in rather nicely, and cable management was fairly easy to do.

A bit strange that they put so much effort into the black and red colour scheme, but then have random coloured fan/f-panel wires. The front panel itself could probably be improved.

Alright so first things first. It's an exceptionally good looking case. Sleek, not cluncky like most out there, with just enough color to suit my scheme. I also love the side window and the In win logo is really cool. The mirror-like face of the case is absolutely goergous! Other than that It's my first build so I can't possible judge if there actually are better cases for the price range but I can say that with my little experience the case could be better for its price for the following reasons: First of all a thing that weird me out was the slots where the gpu comes out from the back of the case. Except for the first slot panel, the other 6 were of the "breakable type", meaning there are no screws to take them off but you actually have to BREAK THEM OFF and you can never put them back! I though that only old cases were still like that, and I couldn't see anything similar in tutorial videos so at first sight I had no idea what to do and I was to afraid to push them hard in fear of breaking them. But that was the point lol! Also another weird thing is the case fan cable. Well the cable ends in 2 connectors, a 2-pin one and a 3-hole one. I guessed that the "3-hole" one connects to the 4-pin fan header on the mobo. There other is still a mystery and I have yet to connect it somewhere but at least the fan and the leds work fine. Also In Win's site suggests that the case has plenty of space in the back for cable management but I can say that I had some trouble fitting the cables and then putting the back panel on without squeezing everything. And to top all that the manual provided is kinda vague...It mostly has intrigate pictures with no text explaining them and It's very hard to make out what it means, not to mention that there are no instructions for the case fan cables.. Overall It's a goergous case and I guess it was worth the trouble but I'm scared to suggest it to a beginner like me.

Well this is controversial one, because there are cases out there that liked and really considered like nzxt s340 or corsair carbide 400c or inwin 805. None of the above had 5.25 external bay, which is what I need for an optical drive. I know I'm a bit old fashioned maybe because more and more cases don't have one these days and within couple of years they might completely disappear. I do use my cd/dvd writer to burn files or music from time to time. Old school I know :) anyway I decided to go with this case not only because of that, I do simply love the way it looks!! in win know how to make a good cases. Only cons I could think of is like mentioned before in other review. expansion slots covers, you actually have to break them out to install gpu etc. you can buy slot covers to replace them tough. And there is no gap on the top to feed 8pin cpu power connector trough, so that one have to go trough same way as 24pin connector. Other than that I would still recommend this case even for first time builders!!!
