>>Added PC Power Silencer 275 ... Great supply, very quiet. CPU fan makes a lot more noise than the supply. Pricey, though.

you just squeeze the two spring-like flanges inward and the nut pops out the back side... I had that part figured out. What do you squeeze it with? A standard pair of pliers will not work. If the cage nut is near a wall you cannot get any lateral force on it. If it were accessible one could push the two flanges in with two small screw drivers. (the case came with an additional fan... will see if I need it.) I spent most of the day playing with fans. The Super Micro SC750A CS-17 case came with three fans including the power supply fan. It sounded like a vacuum cleaner when I turned it on. I picked up six more 12 V fans at a local computer store. Four 3.15 in SQ by 1.0 in W brushless ball bearing 30 cfm 27 dB and two 2.36 in SQ by 0.79 in W 14.5 cfm 26 dB brushless ball bearing...$9 each. I was amazed how easy it was to install them, The 3 in fans just snap into the plastic holders that came with the case. There are two more holders so I will probably pick up two more three inch fans. I bent a small sheet metal strap and mounted one of the small fans blowing directly on the harddrive. Why so many? I am trying to quiet the thing down and keep it clean. I wire a pair of fans in series. This halves ( I think I am right this time...come on back Howard, I miss your quality posts) the voltage and causes the RPM to drop and the fan gets a lot quieter. It also moves less air. To compensate for the reduced air flow I use more fans. I also plan on adding 3M filtrete filter cloth to all of the intake fans. This will decrease the air flow too. I want positive air pressure inside the case. This will require enough intake fans to overpower the exhaust fans. I want all the air coming through the filters. I don't know what to do about the power supply fan. It is now the noisiest of the bunch. It is probably not a good idea to slow it down. Replacing it with the PC Power and Cooling Silencer would work but I am not prepared to do that yet. Maybe it will quiet down with the sides on. Zeuspaul

Paul Thanks for posting: "Comparison of Graphics Cards with NVIDIA's RIVA TNT Chip". I'd just read a glowing review of the STB Velocity 4400 card and had it at the top of my dream machine graphics card list. Your post saved me some unnecessary problems. >>I picked up an Addtronics 6890a medium sized tower ($80 COD, w/o power supply), its the next size down from this tower..<< I'm still stumbling and fumbling trying to figure out what case to go with, so if you don't mind, I'm wondering why you chose to go with the Addtronics case instead of XYZ's case? >>I've added the PC Power & Cooling Silencer 275 ATX power supply $119... (I wanted a quiet 34db unit... also the fan has ball bearings.)<< Sounds interesting! But raises further questions :-) Several years ago I had to replace the p/s in my system and the OEM I bought it from had no idea what p/s was in my system. They sent me one but the location where the switch was and where the wires came out of the p/s didn't match the original. The second p/s they sent me still wasn't exactly right and I ended up having to splice some of the original wires onto the wires of the new p/s. What did you have to go through in order to get a p/s that was configured properly (location of wires, switch, etc.) for the case you bought? RE the hardware for mounting the p/s in the case: Did the mounting hardware come with the p/s or do you have to order it separately? TIA - Emory
