H220 was a good unit for me, for about three months.
Radiator is solid, tubing is good and included fans aren't horrible. You get a six-way PWM splitter, allowing you to run six four-pin fans off one motherboard header.
My pump failed after three months. Gradual build in grinding noises, then one day the bearing just ceased. There are other cases, but I can only speak for me. It looks like a DDC on the block, but it has nowhere near as much power. I was a bit trepidacious of adding another block/rad to its loop to be honest, so the failure was probably a sign from the heavens.
While I had it temps were good, mid 50s on a 3770 at load. I never got to expand it, but I bought it for that reason.
Speaking honestly though, I'd say you were better off looking at a custom loop kit now if you're planning the GPU route in the future. I returned the H220 for the XSPC kit linked below, which turned out to be a very good introduction into DIY loops. The 240 rad will be ample for your CPU, but I would definitely add another 120 or 240 when adding your GPU (base this decision off your GPU TDP).
I can't really say a bad word about the H220, even after returning it. It looks awesome and ran well, and if you win the factory lottery you're probably in for a comfortable few years. Swiftech's support was great for me, even in Australia. I just think an AIO will be a waste of money for you, and you're better off kitting yourself out with decent gear (thicker rads, D5 pump, proper fittings etc.) in preparation for your DIY work down the track.
I've done a few custom loops now. It can be a black hole for money if you don't make sound purchases to begin with. If you're planning to expand it, I'm not sure it's a sound purchase
I'm still using the same pump I got with that kit, can't go wrong with a D5.http://www.pccasegear.com/index.php?mai ... s_id=27264
