OnMouseOver In Unity

Question

quick question I got this script here to show the name of an Item you collect. These names are made public so I can change them within the item list. What I want to do Is to walk into an item and hover my mouse over the item so it can display the name of the item in the middle of the screen. I don't know if I should use a trigger, or a GUILayout or however. Please Help and thanks. Here is the Script: UPDATED

public class RayCasting : MonoBehaviour
{
public float pickupDistance;
public List<Item> items;
//public List<Keybutton> buttons;

#region Unity
void Start ()
{
    Screen.lockCursor = false;

    for (int i = 0; i < items.Count; i++) {
        Item temp = items[i];
        int randomIndex = Random.Range(i, items.Count);
        items[i] = items[randomIndex];
        items[randomIndex] = temp;
    }
}
void Update ()
{
            RaycastHit hit;
            Ray ray = new Ray (transform.position, transform.forward);
            if (Physics.Raycast (ray, out hit, pickupDistance)) {
                    foreach (Item item in items) {

                            if (Input.GetMouseButtonDown (0)) {
                                    if (item.gameObject.Equals (hit.collider.gameObject)) {
                                            numItemsCollected++;
                                            item.Collect ();
                                            break;
                                    }

                            }
                    }
            }
    }

    GUI.backgroundColor = Color.blue;

    }
    else

Attach following script to every item. It will show QUI.Box when mouse hovers the item. Just change the size of the QUI.Box and set the message to suitable values.

using UnityEngine;
using System.Collections;

public class HoverGUI : MonoBehaviour {

    public string message = "Foo Bar";
    public float guiDelay = 0.1f;

    private float lastHoverTime = -99.0f;
    void OnMouseOver() {
        lastHoverTime = Time.timeSinceLevelLoad;
    }

    void OnGUI(){
        if(lastHoverTime + guiDelay > Time.timeSinceLevelLoad){
            GUI.Box(new Rect(0,0,170,250),message);
        }
    }
}
