I have gone through 4 SFF barebones from Shuttle and I have to say they have to be the best out there. The ICE cooling system from these barebones works wonder, considered the size of the case. I like the idea of being able to suck the CPU heat right out of the case instead of blowing it around inside and try to get it out with another fan.
For overclocking, these won't do extreme overclock due to the limited bios settings. But you can still do very decent OCing with them. Here are some of my experience:
- First barebone - no OC because no options being offer in bios ( was a pentium III barebone)
- Second - AMD athlon XP running at 183 mhz bus ( from 133) on barebone SN41G2
-Third- Opteron 148 running at 11X250 mhz bus on barebone SN95G5 V3 ( when I put this same cpu into a case at home I can get it up to 11X270 mhz. I think the limit of the SFF here is the ability to add voltage to the Nforce chipset in the bios)
-Fourth and current Pentium 4 3.06 mhz socket 478 at 23 X 153 mhz on SB61G2 V3 barebone( some may ask me why i step back from the Opteron system- it is because I need the hyperthreading for what I am doing right now with the SFF and I didn't want to spend more moneys on a dual cores Opteron)When i ran this same cpu on an Asus motherboard, I could only do 23 X 145 most.
I just sold my SN95G5 case on ebay and kept the Opteron: item #8768330041
In my last 2 systems I had a 200gb 7200rpm HDD, a DVD recoder, a WIFI card, and an ATI X850XT PE AGP in them and they both run perfectly. The PSU in these SFF are very well built and can handle more stuffs than you can imagine. Just do a search on google and see what video card others ran on these SFF. You will be surprised!

The ICE cooling system from Shuttle is genius. The only draw back on these systems is the noise of the fan if you are going to overclock on it.
