I have a complex operating system issue which involves me needing a new PC for a couple of months, basicaly I need a Windows 2000/XP Pro system capable of running Visual Studio 2003.NET and thats it. I had thought about buying an old base unit but the cheap PII 450s are not capable or running VS smoothly so I have decided to buy my own as it will work out cheaper. I propose to build one the following systems: Althlon 1800 and motherboard £66 new Silver case £18 new 256MB RAM £25 new 80GB HD £35 new 32X CDRW - already have floppy already have Cost to build £144 - a bit steep! system 2 VIA 800Mhz CPU + Motherboard £40 new Silver case new £18 192MB DIMM (already got in) 1 x 4.3GB HD (already have) 1 x 3.2GB HD (already have) 32X CDRW - already have floppy already have Total cost £58 system 3 Althlon 1800 and motherboard £66 new Silver case £18 new 256MB RAM £25 new 1 x 4.3GB HD (already have) 1 x 3.2GB HD (already have) 32X CDRW - already have floppy already have Cost to build £109 The problem is I have not much money so when I sell it I idealy need make at least break even on it. How much would you say each base unit is worth? I tend to sell it with Madrake Linux.
