Go for the Soltek SLKT400 motherboard based system.
CTX monitors are ok but see if you can have the 17" Iiyama Vision Master Pro 413 (HM703UT A) 3 Year Warranty - DiamondTron M2 - 0.25ag - 1600x1200@75hz … after all, this is what you’ll be looking at all day.
The AMD 2000+ is fine (you could afford the 2400) … you will need a good HSF (HeatSinkFan) Their Global Win CBKII58 (Skt A) Supports: Duron / Athlon / Athlon XP 2700+ is the best they do but will do the job fine.
The memory is correct, you really do not need anymore, but it can be added later if you do.
The HD is wrong … never pick a 5400, always go for a 7200rpm … The DiamondMax Plus 9 is a good choice, its also an ATA133 HD. Another is the 80Gb W/Digital WD800JB Special Edition WD Caviar - 7200 RPM - 8MB Buffer.
60gigs are cheap, get one.
The Radeon is a good graphic card. Good choice.
I have had a problems with the Sony CDRW’s (they don’t burn everything) … Go for the Lite-On 48x12x48
Nope, not the XP Home Edition … Go for XP Pro, again, you’ll get all the extras that you may need in the Pro version.
Last … is the case … CCL have a very nice one, the “Blue Nokia” Style Midi Tower (350W) Front Access USB ports and a very good 350W PSU
Mucks.
