  1. Recently I got hold of a iMac 24in early 2008 from a recyling centre (my workplace) for £30, the power supply was toast so I bought one from eBay for £80 and all is working great now, my main computer is a quad i7 4770k with a gtx 780 3gb, should I sell the iMac and get a newer one or leave it? I'm studying biology and chemistry just now so a nice clean no fuss workspace is a must for me, I'm thinking it would be pointless to try to get a more powerful iMac given the fact I have a really powerful dual boot hackintosh 5ft away, from people's experiance, will the iMac (2.8ghz) be able to preform well in 2015 with Yosemite and a few productivity and study apps now and again, or should I just sell it, save a bit and get a newer iMac??

  2. Hi everyone, recently I posted my PowerMac G5 Mod up to the insanely mac forums and though I was generally happy with the mod I have started to think I could off integrated it much better. Heres the thing, the reason why I like apple is the clean no fuss design they incorporate into there machines, the reason I like PC's is the unbeatable value of the hardware I wanted to mix the two together seamlessly, add my own little touch too it and have fun creating a unique machine that has everything I wanted in a desktop computer and more. My previous attempt (pictures Bellow) has the value of PC hardware, the sort of look of a mac and it was fun to make, but again those two elements just didn't mix well I don't think, so i have set out to attempt one more G5 mod to try to get it right. :)


    Here is my previous G5 Mod.

    This time around I will be focusing on the materials used during the Mod and final finishing touches such as using black neoprene tubing instead of PVC and trying to convert more of the original features instead of replacing them ( ACBell PSU, PowerButton, Back PCI slots, original Molex/SATA cables, Delta fans Ect) 


    I have started with converting the original ACBell G5 PSU, Even going so far as to keep the original white power inlet and the original PSU fans.

    Yesterday I finally got my hands on a 1.8GHz Dual Powermac G5 :) I started by striping all the original G5 components out at work. i removed all the G5 motherboard standoffs bar one that supports the midsection divider, the longer standoffs where disgarded and the six shorter ones where reused as standoffs for my Z77 motherboard. once stripped I placed the case and all the metal pieces in the bath and used the shower on a high setting to clean the case and dividers.

    Next I focused on lining the motherboard up with the PCI slots on the G5 and fitting the back CPU fans. I found using dual slot graphics card helped a lot in lining the standoffs and PCI slots up. once lined up I will use pen ink on the flat bottom of the standoffs and line the board back up once five minutes have passed I will remove the board and standoffs and place a blob of epoxy resin on the standoff markings, reinsert the board and standoffs and wait for it to set.

    Next I though a little bit of cable management was in order. it is extremely important for me with this mod to keep the whole look tidy and neat no stray wires so that it ties in with the feel of the original G5 system  :)

    For the liquid cooling system I needed a control centre for water tempreger and fan speed / fan control these things are usually not part of a home made water cooling system or are managed through separate systems, fan speed controllers and thermometers not software, however I recently got my hands on a damaged Antec kuhler h2o and spotted a opportunity, it came with the black fan cables cut and leaking, I opened the unit cleaned out the gunk and made it water tight, thankfully there where printed pinouts on the board for the PWM fans so I hooked up a spare PWM fan and loaded the Antec Chill Control software and it all works great :) once properly configured the antec unit will be grafted onto the home made water cooling loop I own, plus with the addition of two 120MM PWM fans hopefully I will have a fully automated software controlled water cooling loop for my hack :D.

  3. Hey there I had a old system bundle lying around so for curiosity sakes I installed mountain lion 10.8.2 on it to see how well it coped, the specs are as follows.


    motherboard - P5KPL-AM 

    Cpu - Core 2 Quad Q8300 

    Ram - 2X2GB DDR2 667MHz

    Video - ATI HD 5570 1GB of Memory 

    HDD - Western Digital 160GB 7200RPM Sata ii 

    WIFI - Atheros AR9285 a/b/g/n 


    Once installed and I sourced all the device drivers the system felt really snappy despite its relatively low Xbench score of 90. (with multithreading and Hard drive benching turned off. For some reason Xbench crashes on 10.8 if multithreading is enabled) All the GUI effects seemed really fast and startup was fast as well. So after that i decided to reinstall 10.8.2 on my main system it didn't seems as fast or snappy as the Q8300 system at all, longer startup times and longer application start up times, and thats very surprising considering its specs 


    Motherboard - GA-H77N-WIFI

    Cpu - Core i5 2500K

    Ram 2x2GB 1600MHz Corsair XMS3 

    Video ATI HD 5770

    HDD - Western digital 1TB 64MB Cache Sata ii 

    WIFI - Replaced MINI card Atheros AR9285 a/b/g/n (the original mini card that came with the motherboard wasn't compatible with os x 


    The Xbench score was 398 for this system (With the same two options disabled).


    What I'm wondering is this, despite the fact the Q8300 is generally a lot slower than the i5 is it optimised in some way for faster smaller operations. and on the other hand if i used a multithreaded program the i5 would shine wheres the q8300 would choke. But on day to day programs the Q8300 seems faster strangely.









  4. Hi there :) well i bought a £2 usb 3d sound card off Ebay for my Hackintosh and i must say I'm blown away :o!!!! i expected basic,distorted and rubbish audio BUT! this thing sounds better than my £100+ creative audio cards I'm hearing details that i have never heard before in my music and everything sounds perfectly balanced it amazing! what I'm hear to ask (punt) is this, is it the sound card or core audios processing and the cpu as the sound card isn't really accelerated. 


    Thanks for any replies :)
