No. It's a bad candidate. Don't bother, just use Linux.
The issues are
1) All IDE, no SATA
2) 1GB max memory(Windows 7 x86 requires at least 2GB to run well)
3) no Windows Vista drivers
4) It may be difficult to find a processor with Hyperthreading with a 533MHz front side bus to put a appropriate processor in for Windows 7
5) cannot upgrade the onboard video with a AGP card, have to use a PCI card to upgrade video
Don't put Windows 7 on this. This is better suited to run Linux.
