Acer Veriton M464

Easy to set up.

Reliable Quad core machine. Good value. Fully supported using Suse Linux as dual boot machine (installation requires some expertise though).

Preloaded Vista is 32 bit whilst processor is 64bit.

Very user friendly

Some difficulty in formatting live file system found

It's got everything I want and more it's responsive, quiet and looks good

As yet I haven't found anything that I don't like

Decent processor, big hard drive, adequate memory with room for expansion, comes with XP downgrade essential for me, quite a lot of PC for the money. Plenty of expandability.

Case is a bit ugly. Comes with Vista loaded but rolling back to XP was quite easy.
