After bowing to all the pressure I will list my specs!!
My main computer is a Shuttle SD37P2 SFF barebones which has a 975X motherboard and a 400W PSU. I currently have a Q6600 at 2.92GHZ on stock volts,with 4GB of PC2-6400 Geil Black Dragon DDR2,a 320GB Samsung Spinpoint T and a 500GB F3 and an HD4830 with an Akasa Vortexx Neo.
My other desktop had an E4300 at 3.16GHZ(the E2160 has now replaced it for the time being),4GB of generic PC2-6400 DDR2,a 250GB Spinpoint P series disc,a P35 based Asus P5K-SE,an HX520W and an HD3870 with a VF900 on it all in an Antec NKS4000 case.
My computers are getting old but they still do the job.
TBH,my second computer is too big and it would be nice to downsize it into a smaller case. Nice if someone had a SG01,SG02,SG03 or SG04 they could give me for free!!
