Ok so lets start with the power supply; Since you asked for a high quality PSU, i'll link to some good 80+ gold and Platinum ones; of course the 80+ Bronze and Silver are good too so if you find the ones below to be expansive then let me know and i'll refer you to some Bronze and Silver models.
80+ Platinum
Seasonic SS-760XP2 ATX, This is a Platinum PSU and comes with 7 Year warranty and sells for $179
Corsair AX760, Everything on this is identical to the one above, in fact its the same PSU built by Seasonic for Corsair. Also comes with a 7 Year warranty and and sells for the same price of $179
I did not link any 600W+ versions since there seems to be an issue with the platinum models.
80+ Gold
Seasonic X650, 80+ gold, Modular and sells for $119
Corsair HX650, Modular, 7 year warranty and sells for $119, $99 after rebate.
Seasonic X750, Same features as the 650 but is on sale so is also $119
Corsair AX750, same features as the others, sells for $149, the HX model is also Gold but is $10 cheaper.
Corsair AX850, 850W, same features and sells for $169 this is a sale price so its the same price as the HX version.
Seasonic X850, This too is also on sale for $159 and comes with a $20 rebate.
I personally don't think you need Platinum, Gold is pretty high end as it is. I suggest you go with 750W and up, this will future proof you when you upgrade GPU or if you decide to sli/crossfire. Also note that there are other PSU manufactures but i don't have much personal experience with other brands. If these prices are to expansive, we can go with 80+ Silver or Bronze.
Thats fine, If you like the Phantom design then i suggest the 630 over 820, both are full towers and the test review i posted earlier shows that the 630 preforms better then the 820. Other options include Thor V2, or the Full Tower HAF cases. Another case thats been getting good reviews is the
Thermaltake Chaser MK-I, this is a full Tower case and supports new hydro coolers like the H110 by corsair.
Closed Loop Liquid Coolers:
Corsair H60 2013 Edition - $79
Corsair H90 - On sale for $89. If you get a case that has a rear 140mm fan, then i recommend going with the H90 over the H60.
Corsair H100i - $124
Corsair H110 - arguably the top closed loop liquid cooler on the market. Sells for $129 but due to the design, most old cases will not support this. If your interested, then let me know after you pick a case and i'll find out if its supported. The Phantom 630 is Supported.
Nzxt Kraken X40 - Similar to the H90 by Corsair, uses a 140mm fan and mounts on the rear. Current price is $99 and tests show it tends to be louder then the H90. I would recommend the H90 over this model since its cheaper.
Nzxt Kraken X60 - Currently competes with the H110 for the top spot, like the X40 the fans on these are louder then the Corsair models. Currently on sale for $99 and this one does fit in a Phantom 630.
These are it for air coolers, since your going full tower i would recommend something like the H110 or H100 over the smaller models.
AIR:
Xigmatek Dark Knight II Night Hawk Edition - This is a good Air Cooler for its size, its not really small but not insanely huge like some of the other ones. It won't proform as well as the really huge air coolers or the liquid but it does in the same range. Sells for $49
Noctua NH-D14 - In the top 5 air cooler range, comes in a push/pull setup with Noctua fans so tends to the quiet. Is on sale for $79
Deepcool Assassin - This is the one with the green fans in the above pic, also one of the top 5 air coolers. Unfortunately these are not on newegg so i don't have a price for you.
I'm heading out but i'll look up a few more Air coolers if thats what you choose and want more options. Also the AM3 and AM3+ use the same design so anything that supports AM3 will fit AM3+.
