I'm planning on buliding one of these, read alot about the noise level being a bit high......just how high is it? i had people telling me about how loud the delta was......i don't find THAT loud.....is this comparable? also, any insight into this case would be great!!

You also want to look out that the mini-pc comes with a good motherboard, mite want to look around for some reviews. My guess is the shuttle ones prolly have the best preformance out of the other mini pcs..

It's noisy because of the ridiculous 40mm power supply fan that spins at high rpm. The result isn't just high db, but high frequency as well. You can do some modifications to lower the sound though, but be prepared to do some serious work on this case.

No. The classic Delta "black label" 60mm fan is noisier, IMO. However, people usually keep the Shuttle mini systems on the desk right next to the monitor while larger tower cases often sit on floors below desks. This means that what noise the mini system puts out is right in front of your face.

The SS50 that FenrisUlf linked is put together a bit different than the SV25. I have an SV24, which is just like the SV25 except mine doesn't support Tualatin chips. Some, but not all of them have relatively noisy power supply fans. There are a few easy mods that can make it much more quiet, whether or not you have the *noisy* version.

#1 remove the power supply fan. Now, some people have had their power supply die. Just removing the fan probably isn't a good idea. What I've done is to remove the fan while making the power supply run COOLER. How I've done that is while removing the fan, one side of the power supply needs to be removed. I leave that side off, plus cut away part of the plastic flap inside (to keep stuff from grounding out, I guess). I then put the power supply back, but rotated 90º so that the open part of the power supply faces down while the closed side faces up, against the bottom of the floppy drive bay. I hang the power supply using some paper clips, but it can be attached in whatever manner you can think of. Just make sure that you clean up cabling because you don't want anything touching any component inside the power supply. One last thing I do is to put something (I use split-loom tubing) around the wires coming out of the power supply so that they don't get cut by the edge of the power supply box (kinda like all power supplies have grommets around the hole that the wires come out of). This works well in the SV24/SV25 cases because the ONLY place that air comes into the case is through the little holes at the bottom front. With the power supply thus suspended, cool air is drawn past the power supply heatsinks as it travels through the case.

#2 install the hard drive where the floppy drive goes (you'll have to lose the floppy drive). This way there is more room in the rear around the fan area

#3 use a good, quiet heatsink, such as one of those Zalman "flower" units.

#4 make a fan duct for an 80mm quiet fan to exhaust out the normal rear location. Speaking of... cut out the stamped grill in the back and use a wire finger guard. The ducted 80mm fan should fit if you leave out the hard drive bay. Find something to cover up the hole where the hard drive bay normally resides.

I've done those four things to my SV24 and, in conjunction with a Seagate Barracuda IV hard drive, it is almost inaudible. People are amazed when they (try to) hear my system running.

Do you have pics? I'd love to see what you've done!

I didn't need an optical drive for what I use it for, thus the method I used to mount the hard drive. If I were to do an optical drive, I would just mount the hard drive in the floppy drive bay (still using a Seagate, but these days the faster Barracuda V is available in 60 and 120GB, plus an 8MB cache 120GB :D ) and the optical drive in the 5¼" bay. Now, if you don't already have a favorite optical drive, shop around (as in, in person) for a _short_ optical drive. If you compare different brands of CDROM drives (CDRW/DVD/whatever) you'll notice that from faceplate to IDE connector, different brands have different depths. Shorter ones are better for the reason that it leaves more space in the rear of the box for larger fans with ducting. The fans are the most important part because normally they're the most noisy part of the system. After that, the hard drive.

I had an SV25 and they are not silent by any means. The 40mm fans are noisy. The price you pay for SFF PC's. You might want to check out the forums over at SFFTech, which is the popular stop for Shuttle's and similar style. Some people do some fan mods over there with success.

I got an Iwill XP4 now, and it uses an 80mm fan in the PS, but still makes noise. I replaced that stock fan and put a simple 3 position fan controller from Crampusa for $4.99 which got rid of the stock whine a bit. Definite improvement.

You might want to look at the Icube which is just a few bucks more than the SV25 and takes 400MHZ FSB Intel's. Should outperform the SV25.

Good luck.
