STAGE 1 It all started with this thread regarding a hot deal on a Dell Vostro 200. $419 $29.05 tax $FREE shipping = $448.05 shipped cost Dell Vostro 200 mini tower (NOT the slim version) Pentium Dual Core E2140 CPU fan/heatsink this one looks identical 1GB RAM (two 512MB DDR2-667) G33 chipset board (Foxconn G33M02 minus the PS/2 ports) SATA DVDROM drive SATA 80GB HDD nice mini tower case (probably made by Foxconn) 2x 5¼" optical, 2x 3½" HDD, 1x 3½" FDD, 92mm exhaust, really nice airflow characteristics Bestec 300W PSU, 18A on +12v, has 24 pin motherboard, 4 pin +12v, one FDD and four SATA... NO MOLEX STAGE 2 I had a Celeron 420 (Conroe-L core) that defaults to 1.6GHz on an 800MHz FSB. I "pretested" it on an overclockable motherboard at 2.66GHz on default voltage and it runs Prime95 just fine. Time for a BSEL mod! picture of results I used a small piece of aluminum foil, cut to size, then taped on. It worked! Well, depending... my Abit IP35-E still detected it at 1.6GHz and my ASRock ConRoe1333-DVI/H also still detected it at 1.6GHz which was really strange as I thought it would definately work. However, my Biostar TForce P965 detected it at 2.13GHz so... The Dell detected it at 2.13GHz. Success! STAGE 3 Time to push my luck. picture of results Using "heavy duty" aluminum foil this time, I layered a piece over the original, with tape between them to insulate from each other (actually two layers). If you look closely, you can see that the top "leg" of the original layer tore a little bit, but it was hanging on by a hair! The Dell detected it at 2.66GHz. Success! picture of CPU-Z, etc. Running Prime95, the power usage from the wall bounced between... 70W and 71W, as measured by my Seasonic Power Angel. I think there's plenty of juice left over for a PCI-E video card.
