1) I reserched into the SFX PSUs sometime ago,600Watt review states its maybe alittle more noisy than the 450watt , the SFX cost a lot more money than what i got now , also limited on Connectors for sata ,molex ,
the
Silverstone SFX-L 500W '80 Plus Gold' Fully Modular Power Supply , on pre order looks intresting ,
only 130mm depth .
2) My GPUs , Nvidia GTX 970 being very Good on watts , i have a Gigabyte gtx 970 itx ver & a zotac 970 , the Gigabyte GeForce GTX 970 "Mini-ITX" 4096MB temps underload around 60c Unigine_Heaven-4.0 on extreme HD 1920 x 1080p 8x aa from my old case builds , the zotac gtx 970 card , the target temp is set to 79c in the FireStorm software, can set the target temp to what you like in the software ,more you set the target temp more it ajusts the volts for overclocking ,thats why it always reads 79c in the benchmarks .
3) i been watercooling for 10 years ,now retired from it
,my Parvum Systems case build was the last watercooled build.
4) Modding the top i went for drilling air vent holes instead of cutting most of the top off or cutting out big round holes , i think if makes the top look more better/kepping the beauty of the case & allowes adding different fan sizes for this build, well that just my Own Personal View
With the Nvidia new low wattage Architecture on the high end GPUs 970 , 980 gtx is a great thing & allows the 970 cards underload to only reach around 60c on stock cooling like the Gigabyte GeForce GTX 970 "Mini-ITX .
