Hi there!
Thank you for your interest, I can help. I've got a rather solid
lightweight desktop working for myself and I'd be thrilled to make a
custom version for you. You are invited to contact me directly so we can
find out what exactly is relevant for you now, what your future needs
will be, and make a schedule (shouldn't take much more than a couple
weeks to get things set up). As for price my guess is something around
$3500, including high-end sound card.
I'd love to hear from you! My name's Carlo, I'm 23 from Switzerland, and
here's my email address: capocasa(a)gmx.net
Have a great time!
Carlo
