I got the Pantheon last year to replace a Zalman Z9+ (well I donated this to the families 2nd PC) and at the time I thought it was a good deal at around £40, but a year on I'm looking to replace it. It's not bad internally so much as it does have some nice features, but one USB broke and made my PC restart if I inserted any device into it, and the other ones look like they could also break fairly easily as they're fairly loose. Also the heaphone port on the front gives off a hiss when using headphones which is really annoying.
I will be buying a Corsair 200R in the next week or so, and for £5 more I'm sure it's your best bet. Seems to have everything I need, and the simple design is pleasing for me anyway.
