I've been working with computers since 1985, and until about 2005, I had always built every machine I ever owned, but then I discovered the Dell Outlet, since the company I was working for at the time was a Dell shop. This discovery ended really quickly my desire to build machines, as I could not build an equivalent system for what I could get a Dell refurb'ed system for. Oh I guess I could have gotten fairly close -if- my time was worth nothing.. The machine I just retired, a Dell Optiplex GX620, a Pentium 4D, 2.8Ghz, I bought from the Dell Outlet in late 2005 for $419. Over the years I added memory, a second drive, video capture, several different video cards, and when I retired it, back in February of this year, it was still working just fine, but I had an urge to get something from Dell in the Precision/Workstation class. Did a bit of search and came up two fantastic deals.. A Dell Precision T3500 with a Xeon Quadcore, 4GB of ram, a 160GB Seagate 10K enterprise SATA drive, and an Nvidia Quadro FX580/512mb. This was a Dell Financial Services offlease system, and with the 25% coupon I found on SlickDeals, I got the system for $408, added another $100 and took the ram up to 12GB and dualbooted it with Win7/64bit and CentOS6... This machine will likely last me another 5-6 years, perhaps longer.. Why buy a new system, I ask??
