A Mac mini with HDMI seems like common sense, even if Apple hasn’t delivered so far. But that may change soon, according to AppleInsider, who were told by “two people familiar with the matter” that prototypes of a Mac mini with an HDMI port have been showing up in the inner circles.

One of these prototypes is apparently based on NVIDIA’s MCP89 chipset, but Intel’s ongoing licensing dispute with Nvidia will prevent Apple from using the MCP89 chipset alongside its latest generation of Nehalem-based Core i3, i5 and i7 processors if it is the chipset used in the final product.

This is quite a site to behold. It’s a functional Mac mini, JBL Spot subwoofer and WMF1 coffeemaker shoved into a defunct iMac DV case. And it’s called the iMac CS. It’s bizarre, yet beautiful, like a gift from the Apple store in heaven. Klaus Diebel has done an amazing job.

Yes it’s a coffee-making media server with its own sound system. A custom version will cost you about €300 (or $431), but you can probably build your own for less money.

Apple’s Mac mini server gets rid of an optical drive and gains room for two hard disks. It uses Snow Leopard Server, and has the same 2.53GHz Core 2 Duo processor as the updated 320GB Mac mini.

For $1000 it includes two 500GB hard disks, 4GB of RAM, and GeForce 9400M graphics. The 320GB Mac mini will stay at $800, but has the already mentioned new processor, and ups 2GB of memory to 4GB. The $600 entry-level Mac mini has a faster 2.26GHz processor (was 2GHz), 2GB RAM (was 1GB), and has 160GB of storage (was 120GB).

It’s been rumored that Apple has been readying a refreshed iMac line with something more affordable. This weekend, Google AdSense further confirmed these suspicions as users in the Netherlands were treated to some ads for new iMacs, MacBooks, and Mac minis.

The ads point to a dead link at the Apple Store, and according to Google Translate they read: “Apple’s Newest MacBook. Thinner, lighter and faster! Free delivery. Order today,” “The Brand new iMac. Ultra Thin 20 & 24 inch models. From only €1099 (roughly $1,063). Apple Store,” and “Apple’s New Mac mini. Faster and more affordable than ever. From only € 499 ($723). Order immediately.”

This is interesting. According to MacRumors, this could possibly be the next-gen Mac mini we’ve been waiting for. It seems to correspond to other rumored “leaks” that have been popping up and it sports five USB ports, FireWire 800, Mini DisplayPort, and Mini DVI. Hmmm. Photoshop? Wishful thinking?

This pic also hit AppleInsider at the same time and the MacRumors forum poster has included some alleged specs: a 2GHz Core 2 Duo processor with 3MB Level 2 cache, 2GB DDR 3 memory at 1066MHz and a ATA Super Drive. The question is, are you buying this?
