Hi, my first post

I've just purchased an Acer Aspire Revo R3600 Desktop PC, Atom 230 1.6GHz, 160GB HDD, 1 GB RAM, HDMI, nVidia GeForce 9400 ION, WIFI, Linux
I'm about to embark on building a counter top system and this seemd like a a good system.
I plan to wipe the linux install and go to Windows XP.
Has anyone got any views on using these systems as a mame system?
Thanks
