In the Mediastation we can upgrade the CPU and Mainboards too.
In normally production we offer for the X-76 Pro and Expanded the AMD Sempron 64bit, 3000+ and in the X-88 the Athlon 64bit, 3000+.
Of course, IF you will spend much more, you ( or we ) can install the Athlon FX, dualcore too, but the cost of the ONLY CPU can be from 600 to 1200 Euro! depend what you will install.
The Pro and Expanded models have the new Case with the BIG PC hole:

The only Standard mediastation can NOT upgrade the mainboard because we made the Case for the Chaintech MB only, BUT you still can upgrade the CPU, shocket A, 32bit only.
We will continue developing under AMD CPU and NOT Intel, so If you will install one Intel CPU, the OS Installer will ignore it.
AMD support a lot the Linux community and help us to resolve bugs OS software.
Intel is like the Microsoft, to much closed and really slow for Help support and drivers updating.
MS and AMD are open, for that we will not porting the MS to close system.
