Anyone using one of those ? I read reviews, but I want real life usage here.
Issues with heat ? noise ?
They seem to be one of the sole Small Form Factor PC vendors out there.

Not a lot of noise but a bit of high pitched wine.
When it got hit by a nearby groundstrike I bought a good Nexus Breeze4 and fittted it out. Much quieter

What should the the configuration be for a media streaming server that can service 20 simultaneous connections? I'd just like to know the follwing figures:
CPU (Model and amount of cache)
RAM
HDD (How many HDD's and RAID configuration)

This severely depends on what kind of processing you are planning to do while streaming the media, and the type of media being streamed, and the type of stream you want to offer.
Audio-Streaming is less demanding than Video-streaming.
"Forking"-streaming is less demanding than "on-demand"-streaming. (i.e. its easier to simply forward one input to several recipients than to have a seperate input stream for each client).
"passthrough"-streaming is less demanding than "postprocessing"-streaming. (i.e. if you want to alter the stream or add some DRM, its going to cost you some performance.)
Cheers,
Sebastian

(I'm not an hardware person, so ... )
Is there really a difference ?
I've been using intel CPU pretty much all my PC life, so I can't compare, but in what circumstances I should buy an AMD CPU ?
Are there software issues that can happen by switching from one to another ? ( i know this is a naive question )
Thanks

I've always used Intel apart from an AMD 286 in my parents' first PC (although at the time I think this was a licensed Intel design with AMD acting as a second source) and a Duron in my first PC at this company, which was terrible mainly due to a near-complete absence of L1 and L2 cache, and the support chipset from VIA.
I've never had good experiences with non-Intel chipsets. Obviously Intel chipsets are not an option with AMD Athlon or Opteron processors, since Intel's and AMD's processor buses are completely different. Things may be different now that the memory controller is integrated in the AMD processors, but I still don't have that much faith in VIA, nVidia or ATI AGP/PCI bridge components nor, for example, IDE controllers or the other subsystems of the chipset which make up a complete PC system.
Right now Intel's desktop processors suck. Their processing power per watt of electrical power, and per watt of radiated heat, is appalling, and because they've hit a wall in processor frequency, their poor computing power per clock cycle has allowed AMD to pass them. But I still think an Intel-based system will be more reliable than AMD. On the other hand my experience could be because I've generally known enthusiasts with AMD systems, who tend to overclock their systems and/or load them with every bit of junkware under the sun, which have tended to destabilise their computers.
Both manufacturers try very hard to be compatible with their previous generations and with each other, but processor manufacturers make mistakes just as software engineers do. They both publish lists of errata (errors) in their processors and either put a fix into a future revision (stepping) of the processor or publish a workaround.
One issue I'm aware of right now is that, if AMD's Cool and Quiet technology is turned on, the Windows high-performance counters don't count at a fixed rate - the rate is directly proportional to the current processor frequency. The processor drops its frequency to save power and reduce heat if idle or less stressed. Intel have had this problem on some steppings of the Pentium 4 as well. The current workaround is to turn Cool and Quiet off. The problem affects some games and other applications.

I'm in a reasonable position to answer this, I guess, I've experience of AMD's from K6 through Athlon and AMD64, and Intels from 486 through every Pentium (except Pentium M) up to Pentium 4.
At present, AMD's desktop processors (I'm meaning AMD64 - X2 as well, as the core's pretty much the same) have (IMO) much better development (compilation etc) performance than Pentium 4s. I've built the same project from scratch on a 3GHz P4 and an AMD64 3400+ (clock speed is 2.2GHz) and the AMD took about 2/3 of the time of the P4 - other factors such as disk and RAM were approximately equal (1GB RAM, they both had 7200RPM disks, although the one with the AMD64 was a laptop drive, so might have been a bit slower). Other CPU bound tasks display similar speed differences.
However, I think Intel are probably back on track with the Core Solo/Duo range - the Pentium M's were always pretty good for performance.
Anyway - processor/chipset related software issues? Nah, didn't have any of those.

I recently found my long lost program in a 5 1/4 floppy disk. I am now looking for a drive which can read and transferr the data into another medium. If anyone can help me, I would appreciate very much. Thank You.

ebay is your best bet, I tossed my last 5 1/4 drive out years ago.

My motherboard has 3 memory slots. If I attach 128 MB SD RAM to any of the slot my system shows 64 mb where as if attach 64 MB RAM its ok it shows correct. presently I connected 3 SD RAM 128-128 & 64MB so my system properties shows 192 MB of RAM. Whether it is problem with board or with bios. Pse suggest.
Thanks

Check the motherboard manual, due to the chipset design and memory paging you may have to fit memory in a certain order.

my home machine (winXP pro SP2, AMD 3gig, 1gig ram, ATI Radion 9200 video card, purchased as a Compat Presario S5500UK, had a few minor upgrades since then) has recently (last couple of months) developed the nasty habit of spontaniously rebooting at random. so far i can find no patern to this. on one occasion i was editing a txt file in notepad, about 2 other programs open, and it happened, which seems to rule out system load.
in fact system load (i use VMWare a lot) has nothing to do with this, as far as i can tell.
one week ago i reformatted C: (deleted and recreated the partition) to see if this would help. i did that Saturday evening.
Sunday i reinstalled various core programs i need, but only a bare minimum. the only hardware drivers i installed came from windows update - under the vague hope this would mean they were safe.
on Monday i got my next spontanious reboot.
i had installed VMWare 5.5.1, which installs drivers. that was the only candidate i could tie to the approximate time this started happening so i uninstalled 5.5.1, rebooted and installed VMWare 5.0
everything was fine, until today, when i got another spontanious reboot (Saturday), so just under a week between them, which is about average.
after the reboot windows reports the error about 95% of the time. when it does this the error report is:
Error type : Windows stop error (A message appears on a blue screen with error code information)
Solution available? : No (see Next steps)
What does this error mean? : Windows has encountered an error from which it cannot recover and needs to restart
Cause : Unknown device driver
Computer symptoms : A message appears on a blue screen with error code information (for example: e.g. 0x0000001E, KMODE_EXCEPTION_NOT_HANDLED)
i have just turned off automatic reboot to see if i really get a blue screen, and to see if it gives me any clues. windows is not giving me anything to go on here at all.
how much faith should i put in this error description? is it likely to be software or hardware?
last time one of my computers got this problem it spent 9 months bouncing back and forward between various people, never being fixed, before i finally gave in and purchased a whole new box, this one

The first two suspects are usually heat and bad RAM, although if it only happens once a week, I think that would rule out hardware since bad hardware doesn't take that long to cause problems.

i did think about ram myself, but i am making the (wild?) assumption that running 3 VMWare machines simultaniously, with VS2003 or VS2005 active in two of them would stress test my system ram. after all, i only have 1 gig of system ram.
heat, i had not really considered that. the machine has a large fan which only kicks in when the machine is running "hot", and that is normally silent when there is a problem. assuming this fan is working correctly (certainly it does run) then this would suggest not heat, at least to me.

not neccesarilly, I got an error 65-70hrs into a prime95 marathon burnin test for a CPU OC. Since OS level actions were only in the low single digit percentage range it could've gone weeks before the hardware fault caused a crash.

as "luck" would have it i have brought home an 80gig external USB2 hard drive from work to move some large files back and forward between two machines.
i plugged the drive into the computer after making the above post, using a port on the PCI USB2 card i had fitted. i had the card lying around unused, and more USB ports are always useful.
the hard drive was detected just fine, i accessed it and deleted some files quite happily. then i started a 7 gig data move onto the drive. 2 minutes into the move i got a hard lockup in Windows. mouse would not move, no screen updates, keyboard lights would not toggle, CTRL-ALT-DEL did nothing. i left it 5 minutes, no change.
i was forced to do a hard reset. machine comes up, reconnect the USB drive to the same port on the expansion card and set the same transfer going, this time as a copy, see, i did learn something.
i was getting a terrible data transfer rate for USB2, and then a few minutes into the copy another hard lock! 
i have been using this card for (i think) a few months (under 6) with my USB2 pen drive and webcam without any problems.
this time i connected the HD to a different USB port, one on the front of the machine (so "built in"). i got a much better data transfer rate, and i have now done over 50 gig of data transfer to and from my machine with no problems at all.
i have already removed the PCI USB2 card, since it looks very suspicious. if the external drive was bad why does it work for people at work? why did it work perfectly on a different USB port?
however my big question is, does it sound possible that this card was the cause of my problems? since i have had this experience, and have now removed the card, if i get any more spontanious reboots i will do another reformat, to make sure the machine looses all memory of the card.

I think you may also check your PC power supply, sometimes, the Power supply became unstable due to life time.
I don't know what's the model of your power supply. usually, you have to consider your power supply after any upgrade your pc hardware.
I just have a quick look on your post, you should got two pc, right? using the power supply of stable one to run the other.

I have a set of powered speakers that do not seem to be working. When the speakers power is switched off I can hear sound from the speakers although it is extremely quiet. To hear the sound at a decent level the source volume has to be up extremely high. However when I switch the speakers power on I get no sound from the speakers at all despite the power light indicating the speakers are getting power.
It is my understanding powered speakers amplify the source no matter what it is so I tried connecting the speakers to my laptop as well as my mp3 player but no sound could be heard from either except when the speakers power was off.
Is there any reason this could be happenning or is it a case of broken speakers?

it might depends on the source.
for example, on my iPod, if I use the dock, it has an line-out that if volume "independant", so when I plug it into my amp, the volume will be controlled by the amp.
but if I plug it with the headphone port, I have to be certain that the iPod volume is set at least high to be the equivalent of the line-out.
so, check where you plugged you powered speakers either in a line-out or an headphone port.

I tried the speakers with my portable cd player (yes I even dug that relic out of the cupboard) and with another PC. When connected to the cd player sound could be heard when the speakers were switched on but even at maximum volume the sound was barely audible. With the PC, sound could be heard through both powered and non powered speakers but again even at max volume the sound was barely audible.
All I'm trying to do is establish if the speakers work so I can flog them.

Modern PC sound cards are designed to drive line inputs. They no longer have a power amplifier on them to drive speakers directly. You absolutely need a separate amplifier.
Your other equipment was designed to drive headphones. Headphones don't need so much power to produce decent output. The CD player sounds like it has a greater maximum output than your other devices.
It sounds like the amplifier chip itself has died. The little sound you hear when at maximum volume is probably just leakage from the input.
