2. It’s not ugly.
Not a big deal; besides, I think the Psystar box is kind of attractive.

3. It’s quiet.
I’d be looking to replace my Power Mac G4, which isn’t exactly quiet either.

4. It’s not really cheaper.
The Psystar blows the socks of a mini in all the posted performance comparisons. And it’s a heck of a lot cheaper than a Mac Pro. Software Update is still unresolved - Psystar is already offering updates directly from their site.

5. It’s a Mac
The crux of the matter. If Apple offered a mid-range, expandable, upgradeable, desktop then I wouldn’t consider a Psystar either But they don’t offer such a product and they have consistently refused to for years. So my Apple loyalty (and I’ve bought Macs consistently since my first Mac Plus in 1986) is not what it used to be.

It has nothing in common with that very limited Apple product.

Anyway the Mini is almost totally un-upgradeable and has no choice of video/graphic card

A Tower box is better compared to the Apple Pro towers if anything. Surely that is the attraction of them - potential power, potential spec choice and scope for upgradeability.

The Psystar and any home built FrankenMac, has the ability to be modified to suit the user’s particular needs. The Mac Tower is so very limited.

If Psystar can improve the updating issues, which they appear to be doing, and tweak the fan noise issue, which should be possible with relative ease, then this is going to make the units more appealing still as an alternative to an Apple build.
