I've done a few these past few months.
I should note, this RMA isn't done yet...
Company Name: MSI
Product: GTX 670 N670GTX-PM2D2GD5/OC (two of them)
Warranty Period: 3 years
*
Date purchased: September 2012
Date RMAed: Processes started June 5th 2015
Where it was sent to: Canada, Richmond, BC
Ease of RMA: 3/10
Any extra fees?: Had to pay shipping the first time (standard)
Wait time: 20th of August I have finally received cards that appear to be functional
Details: Receipt not required. I'll preface this by saying that I believe MSI will do right by me in the end, but this should serve as a cautionary tale. I went to Australia in February. My cards were acting up, but 3 year warranty and all that, it can wait. I wish I hadn't. Come back beginning of June, decided to start RMA few days later. I am told only one card has valid warranty. I keep pushing for answers and get none. It's a pair of cards bought in September, should have months left. Provide receipt, etc, it leads to nothing. Warranty starts when they sold to Memory Express. I keep doing applications and eventually the warranty "expires" on both cards. At this point I am fuming. Contacting the RMA and support department over and over, reaching out over social media and using OCN since they have a rep there. People there helped and eventually it was approved as an exception. I should mention that by this point, the computer wouldn't boot with either card. Probably a bad cap or something, but I had already replaced the stock cooler and didn't want to take it off again to find out. Send my 670s there, eventually am told they can replace with 770s. Asked for other options (team red or higher end single card), they offered none, quite happy with 770s to be honest, but I like choice, since whatever I was getting I was selling since I've already upgraded. They didn't actually have the cards yet, so it took about a week to get the cards to my door from approving it. When they arrived I didn't visually inspect them. Tried inserting one. I/O plate bent, broke trace for an audio port on mobo, not critical, but disappointing. Noticed gunk on the back of both cards. They gave me a label to ship them back and are getting another set to ship to me. They are slated to arrive at their service centre Tuesday, so hopefully I've only got a week left. In the end, it took extra effort from me to get this process going and hopefully it will end favourably, but I don't think this should've been necessary. Finally got replacement cards. They're still considering my warranty over, but have given me 90 days on the replacement cards in case there is an issue.
Satisfaction: 6/10
* = MSI counts the three years not from date of purchase, but from the date they shipped/sold to your authorized reseller. So if MemEx has had them for four months, your warranty is four months shorter. Your receipt is irrelevant to them, they track it all.
Company Name: Antec
Product: H2O 620
Warranty Period: 3 years?
Date purchased: November 2012
Date RMAed: July 2015
Where it was sent to: Canada, Ontario, Guelph
Ease of RMA: 10/10
Any extra fees?: Just shipping
Wait time: 2 weeks
Details: Receipt required. I contacted them to ask if I had warranty, because their site wasn't clear on how long I had and the pump was broken, or liquid leaked, not sure, sounded like the pump was running dry. They approved an RMA without further questions or even answering my warranty one. They only wanted the pump/rad back. They didn't care about brackets or fans. I got the newer 650 (BNIB) back. Sadly pump location doesn't work for my build so I sold it. They ended up sending me a second one because I have two 620s, but I only sent one, but they didn't want it shipped back.
Satisfaction: 9/10 (to get a ten, they'd have to provide a shipping label or not require shipping)
Company Name: Corsair
Product: H100
Warranty Period: 3 or 5 years?
Date purchased: July 2012 (got it from Intel Retail Edge)
Date RMAed: 27 July 2015 (opened to support ticket to ask about warranty)
Where it was sent to: USA, California, Hayward
Ease of RMA: 7/10
Any extra fees?: Shipping to the US
Wait time: I shipped on the 10th of August (Monday), received my replacement on the 25th (Tuesday)
Details: Receipt sort of required. I got the H100 from Intel Retail Edge and used that order letter as my receipt. I just wanted to know if I had warranty. They approved it. Temps were getting higher with it, as a reference I tried re-applying thermal paste. No difference. Install the 620 after I took out the H100 and got better temps by a few degrees. The delay in shipping is because Corsair wanted everything. They wanted both mounts. They wanted the fans. I didn't use their stock fans nor the AMD mount. It went into a parts box that was left somewhere. A few emails back and forth and eventually it was said to be OK. I really, really appreciate that, but it seems silly to require those parts in the first place. Only the pump/rad is vital, those other parts are practically worthless. They would've just sat in a box to never be used. They shipped me back an H100i. Good upgrade over the H100, very happy.
Satisfaction: 8/10

They make it very difficult to actually submit an RMA request. Razer quality is pretty shit, but IMO this was at the time one of the better 360 controllers. However after a few months one of the triggers stopped. All the wanted was a picture with the cord cut. These controllers break every 3-6 months; either unresponsive triggers (not registering, pressure sensitivity gone) or busted thumb sticks (stuck or only registering at full tilt, click not working). They always had problems accepting the RMA unit I received, serial didn't match receipt. Always took several emails to explain. Some times they wanted me to ship it, I told them to print me a label since I wasn't paying some 30 odd dollars to ship a 50 dollar controller to the US. They asked for the cut cord picture. I've had a few of these controllers now. Bought the Sabre since last Onza broke out of warranty, but haven't used it yet. Point is, they break a lot, expect to RMA them.

Ease of RMA: 6

They make it very difficult to actually submit an RMA request. So the headset broke and at first they told me I was out of warranty. I kept re-iterating that they need to look at the date on my receipt and their warranty terms. I don't know how that confusion arouse, bad rep most likely. They asked for a cut cord picture. They sent me a refurb unit which worked as expected.
Satisfaction: 7
Hope this is all OK the way it. OP if he's still around should make a google spreadsheet to keep data more accessible.
