got a duron 1ghz/512mb ram/xp, on board everything. it's a web browser/mp3/netradio player - one of these days i'll get round to seeing if it'll play mpeg video..
Got a P2-350@233mhz/256mb/6gb/2kpro system that i use as a downloader (soon to be upgraded to bigger hd to account for larger file downloads), through VNC...
£1100 is a lot to spend on a PC, especially for just the parts you got. if you got a big monitor, all in 1 printer, etc it wouldn't be too bad. But that's what really high performance, quality computers cost.
I have never had that much money to spend on a PC. My main rig is a very overclocked XP-M1600, gf4 ti, Tagan psu, dfi infinity, BH5 ram that i assembled largely from 2nd hand parts from MM, had it water cooled at one point, cost me about £400 when i built it (the chip was new) and it has been a very good pc, still does everything i want it to. It's now made to look a bit silly by the recently purchased £500 samsung R20 c2d laptop - C2d 1.73 (5300?) 2gb ram, vista, 120gb hd, radeon 1250 gfx.
my car cost about £900 all in (v.light scratch gone rusty damage, bargain, repair then mods, i do my own work) so i guess my computers cost more than my car

i'm actually quite worried by this
